Starting yesterday, when I test my new Alexa skills with the Service Simulator, I get the following Lambda response:
[i]Unable to call remote endpoint or the response is invalid[/i]
And when I test these new skills using my Amazon Echo, the history in my Alexa iPhone app shows the following error:
[i]Unexpected Communication Issue ... There was a problem communicating with the requested application. [/i]
I verified that I set the Event Source of my Lambda functions to Alexa Skills Kit.
Prior to yesterday, everything was working fine.
Not sure if this is related: I noticed yesterday that my Eclipse automatically installed a new version of an AWS plug-in. (My Lambda functions are Java 8.)
Thanks in advance for any assistance!
