Description

Once you convert your agent's inbound auth from Sigv4 to OAuth and forget to provide a Session ID, the CLI should return more verbose message such as Please specify session ID or, better yet, generate automatically.
agentcore invoke --bearer-token $BEARER_TOKEN "<your prompt>"

Error: 1 validation error for AgentCoreMemoryConfig
session_id
Input should be a valid string [type=string_type, input_value=None, input_type=NoneType]
For further information visit https://errors.pydantic.dev/2.13/v/string_type
Log: /home/sagemaker-user/agentcore-runtime-quickstart/personalAgent/agentcore/.cli/logs/invoke/invoke-personalAgent-20260414-035442.log

Steps to Reproduce

  1. Deploy agent with Sigv4 inbound auth
  2. Switch auth to OAuth (I was using Cognito User Pools)
  3. Generate validate bearer token and forget to pass session ID to invoke function

Expected Behavior

Either:

  1. CLI generates valid session ID
  2. CLI errors "Error: please provide valid session Id using --session-id

Actual Behavior

Error: 1 validation error for AgentCoreMemoryConfig
session_id
Input should be a valid string [type=string_type, input_value=None, input_type=NoneType]

              Description
              Once you convert your agent's inbound auth from Sigv4 to OAuth and forget to provide a Session ID, the CLI should return more verbose message such as Please specify session ID or, better yet, generate automatically.
              agentcore invoke --bearer-token $BEARER_TOKEN "<your prompt>"
              Error: 1 validation error for AgentCoreMemoryConfig

              Steps to Reproduce
              1. Deploy agent with Sigv4 inbound auth
              2. Switch auth to OAuth (I was using Cognito User Pools)
              3. Generate validate bearer token and forget to pass session ID to invoke function
              Expected Behavior
              Either:
              1. CLI generates valid session ID
              2. CLI errors "Error: please provide valid session Id using --session-id
