Amazon Alexa Smart Home : Unable to discover device



I am having an issue in Discovery.



when I discover devices, it does not appear to be calling the Lambda function that I have defined. The Lambda function is configured on the Skill and the event source is configured on the Lambda function.



I have check from monitoring logs that lambda function is not getting called when I try to discover devices from Alexa interface.



If I try to test same using lambda test interface it gives me the response.



Sample request being made from lambda test interface



"header":
"messageId": "6d6d6e14-8aee-473e-8c24-0d31ff9c17a2",
"name": "DiscoverAppliancesRequest",
"namespace": "Alexa.ConnectedHome.Discovery",
"payloadVersion": "2"
,
"payload":
"accessToken": "some string"




Response I got from my API endpoint is as below



"header":
"messageId": "6d6d6e14-8aee-473e-8c24-0d31ff9c17a2",

If the Lambda function itself is never being called, there is a problem with your configuration. Ensure everything is setup correctly, perhaps start over and follow the set up step by step making sure everything is right. Is your lambda event handler set up right? Does your Handler match up with your exports.handler function in the Lambda config?

I just had the same same issue. No discover requests were sent to my lambda function. The error was that I've entered an invalid application id for the Trigger > Smart Home Trigger.



This needs to be the same value as your skill application id.

Clash Royale CLAN TAG #URR8PPP Firebase Auth - with Email and Password - Check user already registered I want to check when a user attempts to signup with createUserWithEmailAndPassword() in Firebase user Authentication method, this user is already registered with my app. createUserWithEmailAndPassword() 8 Answers 8 To detect whether a user with that email address already exists, you can detect when the call to createUserWithEmailAndPassword () fails with auth/email-already-in-use . I see that @Srinivasan just posted an answer for this. createUserWithEmailAndPassword () auth/email-already-in-use Alternatively, you can detect that an email address is already used by calling fetchSignInMethodsForEmail() (previous called fetchProvidersForEmail() ). fetchSignInMethodsForEmail() fetchProvidersForEmail() When the user trying to create an user with same email address, the task response will be "Response: The email address is already in use by another account." mFirebas

Clash Royale CLAN TAG #URR8PPP Dynamically update html content plain JS So I have a script bound in my index.html, which literally has to fetch an array of jsons from an api, then dynamically update my page when get response. But as a result I'm getting an as the only update of my page. here is my script fetch(url) .then((resp) => resp.json()) .then((resp) => resp.results.forEach(item => fetch(item.url) .then((response)=> response.json()) .then((response) => pokeArr.push(response)) .catch(console.log) ) ).catch(console.log) const filler = () => if(!pokeArr) return 0 pokeArr.map((i,j)=> return `<tr>$i.name</tr>` ) const pokeindex = () => document.getElementById('a').appendChild(document.createElement(filler())) pokeindex() When I'm consoling it, I can see in the console all the responses I get, so I'm at least doing the fetching part right. What's parberakan ? What's pokeArr ? – T.J. Crowder Aug 8 at 12

How to determine optimal route across keyboard

Clash Royale CLAN TAG #URR8PPP How to determine optimal route across keyboard I'm trying to automate the typing process in a video game. Players are given an on-screen QWERTY keyboard layout that they can navigate with the control stick (up, down, left, right) in order to select a letter to type. I was wondering if there was a module for Python (or some other resource I could explore) that would help my program find a path across the keyboard as it types each letter in a given message. In other words, if the first letter typed was "A" and the next letter was "B", the module would know that the program should move 1 space down on the keyboard and 4 spaces to the right. Currently, I have the program resetting to the "G" key after each letter is typed (allowing me to use fixed-directions as the program parses each character in the desired message). As you can imagine, this is quite inefficient and defeats the purpose of automating the typing in the fir
