Issue with AWS Bedrock Agent Service and Cognito Integration

Dear Support,

I hope this message finds you well. I'm writing to report an issue I've encountered while working with the AWS Bedrock Agent Service and its integration with Cognito.

Issue Description: When I hit the Agent created from Postman, it returns a response in bytes. However, the Cognito window associated with the Lambda function gives the proper output. Observations: When the same payload is used, the response shows "failureReason":"LLM prediction format incorrect" from the AWS Bedrock Agent Service. No logs are generated in Cognito's Lambda function every time we hit the Postman request. However, we expect to see the response on the Cognito window of the agent Lambda function each time.
