Description

Hi, anyone has similiar issue ? I just deploy a simple service for a basic REST API, following a tutorial.

but when call it through CURL, it return errors

I have met similiar issue for many times following different tutorials. the only change is runtime from node4.3 to node6.10 and region from us-east-1 to ap-northeast-2.

{ “message”: “Internal server error” }

after revised to a complicated handler, I can GET back data as expectation, but the console show info like “miss from cloudfront”, I think something still wrong, so I want to figure out the root cause.
