Answer 1

In my case i was not returning a properly formatted IAM policy document. My Authorizer function was doing wrong assumptions on how to get some parameters from request, and default result was not proper policy (this was my specific case). I managed to debug it using CloudWatch log service, with traditional logging instructions coming from my function code.
