Handling Internal Server Exception in Invoke_agent in Bedrock

0

I am using the Bedrock invoke_agent API and currently handling errors like this:

except botocore.exceptions.ClientError as e:
    error_code = e.response.get("Error", {}).get("Code", "")
    if error_code == "InternalServerException":
        # handle internal server error

My question is: Is checking the error code with e.response.get("Error", {}).get("Code", "") the recommended way to catch InternalServerException? Or is there a more reliable pattern specifically for handling InternalServerException with Bedrock APIs?

When handling an InternalServerException in Amazon Bedrock's invoke_agent API, your current approach of checking the error code with e.response.get("Error", {}).get("Code", "") is a valid pattern for catching this specific exception.

The InternalServerException occurs when there's an internal server error on the AWS side, with an HTTP status code of 500. When this happens, the recommended action is to retry your request, as these errors are often transient.

In some cases, the InternalServerException may include a "reason" field that provides additional information. For example, if the reason is "BEDROCK_MODEL_INVOCATION_SERVICE_UNAVAILABLE", it indicates that the model invocation service is temporarily unavailable, and you should retry your request.

For more robust error handling, you might want to implement a retry mechanism with exponential backoff when encountering this exception. Additionally, if you're building a Bedrock Agent with Lambda functions, you can return a well-formed response with a custom error message to allow the agent to continue the conversation with the user, or set the responseState to "FAILURE" if you want to abort the conversation.

If the issue persists despite retries, it may be worth reviewing server logs to identify specific error messages or stack traces, and potentially opening a support ticket with AWS if you cannot resolve the issue.
