Workers can now configure the timeout for HTTP requests to the Execution API server via the [workers] execution_api_timeout configuration option. The default remains 5 seconds (httpx default) to preserve existing behavior.

https://www.python-httpx.org/advanced/timeouts/

This prevents timeout errors in high-load environments where API servers may take longer than 5 seconds to respond. Users experiencing timeout issues can now increase this value without code changes.

The timeout controls how long a worker waits for a single API request to complete, which is different from execution_api_retries that controls retry behavior after failures.

Fixes#56571

Add configurable timeout for Execution API requests
fdbb9a7
Workers can now configure the timeout for HTTP requests to the Execution
API server via the `[workers] execution_api_timeout` configuration option.
The default remains 5 seconds (httpx default) to preserve existing behavior.
https://www.python-httpx.org/advanced/timeouts/
This prevents timeout errors in high-load environments where API servers
may take longer than 5 seconds to respond. Users experiencing timeout
issues can now increase this value without code changes.
The timeout controls how long a worker waits for a single API request
to complete, which is different from execution_api_retries that controls
retry behavior after failures.
