I just created a very simple alexa skill with this alexa-app npm module. And called my skill and I get the response "INVALID_REQUEST_TYPE". It's been a while since I've played with this module, but it looks like the values that Amazon is passing along to skills has changed in format. There hasn't been any code changes for about a year. Is this still supported? Is a new version recommended?

ex. request intent passed in from Amazon:

"request": {
		"type": "IntentRequest",
		"requestId": "amzn1.echo-api.request.ad7db8b4-d821-457d-bec0-95d26a3fc5a8",
		"timestamp": "2019-12-16T17:28:26Z",
		"locale": "en-US",
		"intent": {
			"name": "number",
			"confirmationStatus": "NONE",
			"slots": {
				"mynumber": {
					"name": "mynumber",
					"value": "3",
					"confirmationStatus": "NONE",
					"source": "USER"
				}
			}
		},
		"dialogState": "STARTED"
	}
