Unable to execute intents in Alexa Skills
For some reason I am unable to execute a few of my intents in my Alexa skill. Here is the flow of discussion as it is.
- 'open my passwords'
Alexa: what is your passphrase?
- 'my passphrase is test'
Alexa: You're in.
- 'what is my wifi password?'
Alexa: There was a problem with the requested skill's response.
Here is a screenshot of the conversation.
And here are my acceptable utterances, where type is of slot type AMAZON.SearchQuery.
At this point I am just trying to reach GetPasswordHandler and have her say 'hello world'. But I am unable to log or reach this intent. I was reaching it at one point and was able to execute this intent but for some reason it's not working now and I just get the generic There was a problem with the requested skill's response error.
I tried moving around the intents because I thought maybe the order in which they were listed was the problem but I have yet to find an order that works. I also tried using CloudWatch to log whatever the issue might be but I am pretty new to it and I might be using it incorrectly because I feel like the information isn't very helpful aside from the fact that alarms. All I have been able to find out from the JSON Input in the test panel is that the response was invalid. Here is what the error looks like in the input JSON for the SessionEndRequest.
"error": {
"type": "INVALID_RESPONSE",
"message": "An exception occurred while dispatching the request to the skill."
}
This is the input JSON for the initial GetPassword request.
"request": {
"type": "IntentRequest",
"requestId": "amzn1.echo-api.request.bdae78eb-3c92-49a8-b3af-c590e284b842",

Solution
I ended up just rewriting the intents and they work now. I'm not sure exactly what was wrong but I noticed that when I added the new intents they were added to the bottom of my skill manifest as opposed to the previous order. I am not 100% sure that this was the issue but it is the only thing I noticed changing when I remade the intentions.
