“Sorry, I had trouble doing what you asked. Please try again.”
This message comes from the default error handler placed in the skill’s fulfillment code (in index.js) when the project was initialized with ask new. If you see or hear this response, it means that Alexa found a matching intent for your utterance and it attempted to handle the request, but there was some exception thrown from the intent handler.
The exception thrown could be almost anything, depending on what your skill was doing when the exception was thrown. The best way to determine what the problem is (and then fix it) is to add a few logging messages in the intent handler and view the logs in CloudWatch.
It might be helpful to know that you are welcome to change the message in the default error handler to say anything you want it to say. This could be useful in making your skill unique among other skills, even in how it handles errors.
