echo-api | First attempt at an API for Amazon Echo | AWS library

I've been stuck with hosting an alexa skill webserver on my localhost! Everything's correct from the Intents I've made, the url works, and it does request the intent I ask it for, but Alexa constantly keeps saying "There was a problem with the requested skill's response"

I am currently building an Alexa Skill using my own .NET-Backend, which should return an AlexaTextList with dynamic contents from my service. The request by Alexa looks the following:

I'm trying to work through the steps listed here for an Alexa Skill I'm developing in Java.

I'm getting a request from Alexa which is a POST. Two of the headers are the signing certificate chain url and the signature.

Amazon SHA1 hashes then signs the entire body of the Alexa request with an X509 key, and then base64 encodes the signed body. This is the "signature." The signing certificate chain is the url where I can GET the X509 certificate chain that contains their public key.

What I need to do is base64 decode the signature, then use the X509 public key to decrypt the signature. This leaves me with a SHA1 hashed request body. Then I need to SHA1 hash the body of the request myself and compare the two.

I validate the certificate chain. I extract the public key. I hash the body of the POST and produce a derived hash value (its SHA1withRSA). I base64 decode the "signature" then decrypt it with the public key to get the asserted hash value.

I've not been able to produce a derived hash value that matches the asserted hash value. This is where I'm stuck and I can't understand what I'm doing wrong. I don't really understand this encryption stuff very well so perhaps I'm missing something super simple.

Step 8 from the link above is where I'm stuck.

First, I borrowed the code from the alexa SDK here. The problem is this code doesn't seem to work:

I receive the error "There was a problem with the requested skill's response" which is arising from the following class:

I am using an AWS lambda function to serve my NodeJS codebase for an Alexa Skill.

The skill makes external API calls to a custom API as well as the Amazon GameOn API, it also uses URL's which serve audio files and images from an S3 Bucket.

The issue I am having is intermittent, and is affecting about 20% of users. At random points of the skill, the user request will produce an invalid response from the skill, with the following error:

i know, this topic was discussed very often. But these posts are either very old, or do not fix my problem. So i try it with opening a new (other) one. I recently started making Alexa Skills. So now i managed to set up my AWS Lambda function with the help of (an also old) Tutorial. Everything worked fine in the first step. So now i want to sent a GET Request to a website, just to get the status code. In the next step, Alexa should tell me this code- but thats a diffrent story. So i tried to get the request done with many different code snippets- but nothing worked. After reading various posts, i understand that the code runs faster then the request can be executed. So the answer of the request does never show up in the logs. Which means, i cannot make use of it.

This is my current code:

I have created one Alexa skill which I want to communicate with my chatbot. When I am asking question to Alexa, in request only intent name is coming.But I want the utterance text also. Is it possible to get that utterance? "request": { "type": "IntentRequest", "requestId": "amzn1.echo-api.request.480ebab4-cd67-418e-b67f-eb8a00b74020", "timestamp": "2020-02-13T06:55:52Z", "locale": "en-US", "intent": { "name": "ask_utterance", "confirmationStatus": "NONE" } } This is the request.I am correctly getting intent name but i want utterance text which will then I will send to my chatbot. Is it possible to do that?

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.

1. 'open my passwords'

Alexa: what is your passphrase?

1. 'my passphrase is test'

Alexa: You're in.

1. '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.

after setting up everything i am getting this error in while testing the skill in Alexa developer There was a problem with the requested skill's response then i put that json response in lambda test and i got the following
