Payload returned from the AWS SDK is sometimes (particularly S3.Get) encoded in a BUFFER. To parse this to a string pass the output into a function with msg.payload=Buffer.from(msg.payload.Body).toString("utf-8") or similar to decode strings.
Make sure that the AWS IAM User you are using has sufficient permissions for the function you are using. If you dont you will get an error message.
