// You can copy and paste the contents as the code for a new Lambda function, using the alexa-skill-kit-sdk-factskill template.
// This code includes helper functions for compatibility with versions of the SDK prior to 1.0.9, which includes the dialog directives.
// 1. Text strings =====================================================================================================

The code was working initially, but after I made a couple of edits to the Lambda code, I was getting the same reply again and again, which made no sense. I think that the problem may lie in the fact that I added an extra value for the accidental value, and I added a natural value before rebuilding my Lambda code in the skillinator.io site. Any help would be much appreciated as I have been struggling with this code all day.
"There was a problem with the requested skill's response” means that there is something wrong with the response json. It might be null or invalid.
In your case, this line throws an error because your string concatenation is not right.
Change it to :
