I get appropriate and correct output when I use the AWS Agent Test from AWS console.

Accepted Answer

Hi,

Based on this document, it appears the endpoint uses [InvokeAgentCommand](https://docs.aws.amazon.com/AWSJavaScriptSDK/v3/latest/Package/-aws-sdk-client-bedrock-agent-runtime/Class/InvokeAgentCommand/) API from the AWS SDK. As per the documentation, the response is returned in the bytes field of the chunk object. The response is in base64 format.

I would suggest you decode the output using a base64 decoder. Some examples are [here](https://docs.aws.amazon.com/bedrock/latest/userguide/bedrock-agent-runtime_example_bedrock-agent-runtime_InvokeAgent_section.html)

Hope this helps!

Thanks,
Rama
