Question

A developer is building a Bedrock Agent that lets employees check the status of internal support tickets by asking natural-language questions. The developer defines an action group backed by a Lambda function and provides an OpenAPI schema describing a getTicketStatus operation with a required ticketId string parameter. During testing, the agent correctly identifies user intent but the Lambda receives an empty parameter list and cannot resolve the ticket. What is the MOST likely cause and correct fix?

Accepted Answer

The OpenAPI schema is missing accurate descriptions and the required marker for the ticketId parameter, so the agent cannot map user input to the parameter; add clear parameter descriptions and mark ticketId as required in the schema.

Answer

The Lambda function lacks a resource-based policy allowing bedrock.amazonaws.com to invoke it; add the lambda:InvokeFunction permission for the agent.

Answer

The agent must use Provisioned Throughput to pass parameters to action groups; purchase a provisioned model unit and re-associate the agent.

Answer

Action group parameters can only be passed when Return of Control is enabled; switch the action group to return control to the client application.
