When using the "Alexa Emulator" during skill testing, my skill works very well (when typing my utterances). However if I speak the same utterances to my Amazon Echo device, almost always it responds with, “There was a problem with the requested skills response”. I have no way to debug the issue since there's no problems when running the Emulator.
I am speaking very clearly to my Amazon Echo device. I've also tried changing my Skill invocation name, it doesn't avoid this issue.
Also, I didn't see any difference in the cloudwatch logs between the Echo Device and the Emulator.
Example utterances:
"Alexa, tell xxxxx xxxxx to start Michael Jackson Thriller"
"Alexa, tell xxxxx xxxxx to start watching Michael Jackson Thriller"
"Alexa, tell xxxxx xxxxx to start playing Michael Jackson Thriller"
