Error message: Process exited before completing request

Why do I see this?

One of your functions either didn’t call context.done or context.succeed when it finished.

What does this mean?

You have to tell Lambda that your function has been completed by calling the right context methods.

How do I fix “AWS Lambda: Process exited before completing requesterror?

Check if you have calls to context.done or context.succeed in your code and that they can be reached. If this is the case, check if your function has run out of memory (this is evident from the REPORT line)
