@Ryan694, my code is different from yours, but after looking here, I think this might work:

const ExitHandler = { canHandle(handlerInput) { const request = handlerInput.requestEnvelope.request; return request.type === 'IntentRequest' && (request.intent.name === 'AMAZON.StopIntent'); }, handle(handlerInput) { return handlerInput.responseBuilder .speak('bye!') .shouldEndSession(true) .getResponse(); }, };
