API & Infrastructure Integration Diagnostics

Resolve throttling and permissions failures in Bedrock and agent tool integrations.

WHAT

Resolve API integration failures, throttling, and permissions errors.

COMMON ERRORS

  • HTTP 429 (ThrottlingException): backoff with jitter, Cross-Region Inference, or request quota increase.
  • HTTP 403 (AccessDeniedException) on agent tools: agent execution role lacks lambda:InvokeFunction, or Lambda resource policy denies bedrock.amazonaws.com.

Key points

  • HTTP 429 ThrottlingException
  • Exponential backoff with jitter
  • Cross-Region Inference / quota increase
  • HTTP 403 AccessDenied on tools
  • lambda:InvokeFunction for agents

Exam focus

Agent AccessDeniedException on tool execution usually means missing lambda:InvokeFunction on the agent role or Lambda resource policy.
