Hello @tb102122! Thanks for reporting this issue!

I was looking at the error and the code and I think the problem is related to the type of data you are trying to log in the logger.debug("Received event: " + json.dumps(event, indent=2)) line.

I have some questions to help me understand better the problem:

1 - Are you using custom runtime or docker images with Lambda?
2 - Can you share with me the payload? Please remove any sensitive data.
3 - What the experience you're trying to have here? You want INFO level, DEBUG level or switch between them when executing your Lambda?

Thanks

sorry yes you are right the formatting was wrong.
