Garbled text from context.http.get as source of AWS SES emails

So submit a support request then.
If it is an issue that was introduced within Atlas Functions, then I highly doubt a fix will be made for your specific use case (which is why I suggested an alternative like axios).

The bottomline is, it’s not working now, so something changed to break the existing functionality. Was it context.http.get? Was it the aws library? You need to test different scenarios to pinpoint where the issue occurs.
