“You just triggered {Some Intent}.”

This message comes from IntentReflectorHandler, the intent handler included in index.js when the skill was first initialized. It indicates that although you have defined the intent in the interaction model and the utterance was mapped to that intent, there is no intent handler defined to handle the intent. Or, if you have defined an intent handler, it has either not registered with addRequestHandlers() or it has been registered after IntentReflectorHandler.

You can fix this by making sure you’ve defined an intent handler whose canHandle() method returns true for the given intent and including it before IntentReflectorHandler in the call to the skill builder’s addRequestHandlers().
