Add workflow health CLI command and web functionality

[TooTallNate]

Web:

CLI:

Added health check functionality to both the CLI and web UI to verify workflow and step endpoints are operational.

What changed?

• Added a new workflow health CLI command that checks the health of workflow and step endpoints
• Added a Health Check button in the web UI that performs queue-based health checks
• Implemented server actions to support health checks from the web interface
• Created shared types and utilities for health check functionality

How to test?

CLI:

# Check both endpoints
workflow health
# Check specific endpoint
workflow health --endpoint workflow
# Set custom timeout
workflow health --timeout 60000
# Get JSON output
workflow health --json

Web UI:

• Click the new Health Check button in the top navigation bar
• Toast notifications will display the results of the health check

Why make this change?

This feature helps users quickly verify if their workflow infrastructure is operational, especially in environments with Vercel Deployment Protection. The queue-based health checks bypass deployment protection to provide accurate status information about the underlying infrastructure. This is useful for troubleshooting and ensuring the system is functioning properly.

oof - good catch. also writing to process.env is really messy and prone to so many issues. we really need to clean this up @VaguelySerious

[vercel]

🔧 Build Fix:

The code is trying to access the error property on a ServerActionResult<HealthCheckResultWithLatency> type that only has a success property when success is true. This is a TypeScript type error where the property doesn't exist on the success case of the union type.

🔧 Build Fix:

The code is attempting to access the error property on a ServerActionResult<HealthCheckResultWithLatency> type, but this property doesn't exist on the { success: true; data: HealthCheckResultWithLatency; } union member. This is a TypeScript type error.

[pranaygp]

nice!

[TooTallNate]

Web:

CLI:

Added health check functionality to both the CLI and web UI to verify workflow and step endpoints are operational.

What changed?

• Added a new workflow health CLI command that checks the health of workflow and step endpoints
• Added a Health Check button in the web UI that performs queue-based health checks
• Implemented server actions to support health checks from the web interface
• Created shared types and utilities for health check functionality

How to test?

CLI:

# Check both endpoints
workflow health
# Check specific endpoint
workflow health --endpoint workflow
# Set custom timeout
workflow health --timeout 60000
# Get JSON output
workflow health --json

Web UI:

• Click the new Health Check button in the top navigation bar
• Toast notifications will display the results of the health check

Why make this change?

This feature helps users quickly verify if their workflow infrastructure is operational, especially in environments with Vercel Deployment Protection. The queue-based health checks bypass deployment protection to provide accurate status information about the underlying infrastructure. This is useful for troubleshooting and ensuring the system is functioning properly.

oof - good catch. also writing to process.env is really messy and prone to so many issues. we really need to clean this up @VaguelySerious

[vercel]

🔧 Build Fix:

The code is trying to access the error property on a ServerActionResult<HealthCheckResultWithLatency> type that only has a success property when success is true. This is a TypeScript type error where the property doesn't exist on the success case of the union type.

[vercel]

🔧 Build Fix:

The code is attempting to access the error property on a ServerActionResult<HealthCheckResultWithLatency> type, but this property doesn't exist on the { success: true; data: HealthCheckResultWithLatency; } union member. This is a TypeScript type error.

[pranaygp]

nice!

[TooTallNate]

Web:

CLI:

Added health check functionality to both the CLI and web UI to verify workflow and step endpoints are operational.

What changed?

• Added a new workflow health CLI command that checks the health of workflow and step endpoints
• Added a Health Check button in the web UI that performs queue-based health checks
• Implemented server actions to support health checks from the web interface
• Created shared types and utilities for health check functionality

How to test?

CLI:

# Check both endpoints
workflow health
# Check specific endpoint
workflow health --endpoint workflow
# Set custom timeout
workflow health --timeout 60000
# Get JSON output
workflow health --json

Web UI:

• Click the new Health Check button in the top navigation bar
• Toast notifications will display the results of the health check

Why make this change?

This feature helps users quickly verify if their workflow infrastructure is operational, especially in environments with Vercel Deployment Protection. The queue-based health checks bypass deployment protection to provide accurate status information about the underlying infrastructure. This is useful for troubleshooting and ensuring the system is functioning properly.

oof - good catch. also writing to process.env is really messy and prone to so many issues. we really need to clean this up @VaguelySerious

[vercel]

🔧 Build Fix:

The code is trying to access the error property on a ServerActionResult<HealthCheckResultWithLatency> type that only has a success property when success is true. This is a TypeScript type error where the property doesn't exist on the success case of the union type.

[vercel]

🔧 Build Fix:

The code is attempting to access the error property on a ServerActionResult<HealthCheckResultWithLatency> type, but this property doesn't exist on the { success: true; data: HealthCheckResultWithLatency; } union member. This is a TypeScript type error.

[pranaygp]

nice!

[TooTallNate]

Web:

CLI:

Added health check functionality to both the CLI and web UI to verify workflow and step endpoints are operational.

What changed?

• Added a new workflow health CLI command that checks the health of workflow and step endpoints
• Added a Health Check button in the web UI that performs queue-based health checks
• Implemented server actions to support health checks from the web interface
• Created shared types and utilities for health check functionality

How to test?

CLI:

# Check both endpoints
workflow health
# Check specific endpoint
workflow health --endpoint workflow
# Set custom timeout
workflow health --timeout 60000
# Get JSON output
workflow health --json

Web UI:

• Click the new Health Check button in the top navigation bar
• Toast notifications will display the results of the health check

Why make this change?

This feature helps users quickly verify if their workflow infrastructure is operational, especially in environments with Vercel Deployment Protection. The queue-based health checks bypass deployment protection to provide accurate status information about the underlying infrastructure. This is useful for troubleshooting and ensuring the system is functioning properly.

oof - good catch. also writing to process.env is really messy and prone to so many issues. we really need to clean this up @VaguelySerious

[vercel]

🔧 Build Fix:

The code is trying to access the error property on a ServerActionResult<HealthCheckResultWithLatency> type that only has a success property when success is true. This is a TypeScript type error where the property doesn't exist on the success case of the union type.

[vercel]

🔧 Build Fix:

The code is attempting to access the error property on a ServerActionResult<HealthCheckResultWithLatency> type, but this property doesn't exist on the { success: true; data: HealthCheckResultWithLatency; } union member. This is a TypeScript type error.

[pranaygp]

nice!

[TooTallNate]

Web:

CLI:

Added health check functionality to both the CLI and web UI to verify workflow and step endpoints are operational.

What changed?

• Added a new workflow health CLI command that checks the health of workflow and step endpoints
• Added a Health Check button in the web UI that performs queue-based health checks
• Implemented server actions to support health checks from the web interface
• Created shared types and utilities for health check functionality

How to test?

CLI:

# Check both endpoints
workflow health
# Check specific endpoint
workflow health --endpoint workflow
# Set custom timeout
workflow health --timeout 60000
# Get JSON output
workflow health --json

Web UI:

• Click the new Health Check button in the top navigation bar
• Toast notifications will display the results of the health check

Why make this change?

This feature helps users quickly verify if their workflow infrastructure is operational, especially in environments with Vercel Deployment Protection. The queue-based health checks bypass deployment protection to provide accurate status information about the underlying infrastructure. This is useful for troubleshooting and ensuring the system is functioning properly.

oof - good catch. also writing to process.env is really messy and prone to so many issues. we really need to clean this up @VaguelySerious

[vercel]

🔧 Build Fix:

The code is trying to access the error property on a ServerActionResult<HealthCheckResultWithLatency> type that only has a success property when success is true. This is a TypeScript type error where the property doesn't exist on the success case of the union type.

[vercel]

🔧 Build Fix:

The code is attempting to access the error property on a ServerActionResult<HealthCheckResultWithLatency> type, but this property doesn't exist on the { success: true; data: HealthCheckResultWithLatency; } union member. This is a TypeScript type error.

[pranaygp]

nice!

[TooTallNate]

Web:

CLI:

Added health check functionality to both the CLI and web UI to verify workflow and step endpoints are operational.

What changed?

• Added a new workflow health CLI command that checks the health of workflow and step endpoints
• Added a Health Check button in the web UI that performs queue-based health checks
• Implemented server actions to support health checks from the web interface
• Created shared types and utilities for health check functionality

How to test?

CLI:

# Check both endpoints
workflow health
# Check specific endpoint
workflow health --endpoint workflow
# Set custom timeout
workflow health --timeout 60000
# Get JSON output
workflow health --json

Web UI:

• Click the new Health Check button in the top navigation bar
• Toast notifications will display the results of the health check

Why make this change?

This feature helps users quickly verify if their workflow infrastructure is operational, especially in environments with Vercel Deployment Protection. The queue-based health checks bypass deployment protection to provide accurate status information about the underlying infrastructure. This is useful for troubleshooting and ensuring the system is functioning properly.

oof - good catch. also writing to process.env is really messy and prone to so many issues. we really need to clean this up @VaguelySerious

[vercel]

🔧 Build Fix:

The code is trying to access the error property on a ServerActionResult<HealthCheckResultWithLatency> type that only has a success property when success is true. This is a TypeScript type error where the property doesn't exist on the success case of the union type.

[vercel]

🔧 Build Fix:

The code is attempting to access the error property on a ServerActionResult<HealthCheckResultWithLatency> type, but this property doesn't exist on the { success: true; data: HealthCheckResultWithLatency; } union member. This is a TypeScript type error.

[pranaygp]

nice!

[TooTallNate]

Web:

CLI:

Added health check functionality to both the CLI and web UI to verify workflow and step endpoints are operational.

What changed?

• Added a new workflow health CLI command that checks the health of workflow and step endpoints
• Added a Health Check button in the web UI that performs queue-based health checks
• Implemented server actions to support health checks from the web interface
• Created shared types and utilities for health check functionality

How to test?

CLI:

# Check both endpoints
workflow health
# Check specific endpoint
workflow health --endpoint workflow
# Set custom timeout
workflow health --timeout 60000
# Get JSON output
workflow health --json

Web UI:

• Click the new Health Check button in the top navigation bar
• Toast notifications will display the results of the health check

Why make this change?

This feature helps users quickly verify if their workflow infrastructure is operational, especially in environments with Vercel Deployment Protection. The queue-based health checks bypass deployment protection to provide accurate status information about the underlying infrastructure. This is useful for troubleshooting and ensuring the system is functioning properly.

oof - good catch. also writing to process.env is really messy and prone to so many issues. we really need to clean this up @VaguelySerious

[vercel]

🔧 Build Fix:

The code is trying to access the error property on a ServerActionResult<HealthCheckResultWithLatency> type that only has a success property when success is true. This is a TypeScript type error where the property doesn't exist on the success case of the union type.

[vercel]

🔧 Build Fix:

The code is attempting to access the error property on a ServerActionResult<HealthCheckResultWithLatency> type, but this property doesn't exist on the { success: true; data: HealthCheckResultWithLatency; } union member. This is a TypeScript type error.

[pranaygp]

nice!

[TooTallNate]

Web:

CLI:

Added health check functionality to both the CLI and web UI to verify workflow and step endpoints are operational.

What changed?

• Added a new workflow health CLI command that checks the health of workflow and step endpoints
• Added a Health Check button in the web UI that performs queue-based health checks
• Implemented server actions to support health checks from the web interface
• Created shared types and utilities for health check functionality

How to test?

CLI:

# Check both endpoints
workflow health
# Check specific endpoint
workflow health --endpoint workflow
# Set custom timeout
workflow health --timeout 60000
# Get JSON output
workflow health --json

Web UI:

• Click the new Health Check button in the top navigation bar
• Toast notifications will display the results of the health check

Why make this change?

This feature helps users quickly verify if their workflow infrastructure is operational, especially in environments with Vercel Deployment Protection. The queue-based health checks bypass deployment protection to provide accurate status information about the underlying infrastructure. This is useful for troubleshooting and ensuring the system is functioning properly.

The code is trying to access the error property on a ServerActionResult<HealthCheckResultWithLatency> type that only has a success property when success is true. This is a TypeScript type error where the property doesn't exist on the success case of the union type.
