Nuxt Page this.$axios.CancelToken is undefined - axios

I'm trying to get an axios module CancelToken generated using the following on a create hook inside a page.
created() {
const source = this.$axios.CancelToken.source()
...
But I get
TypeError: "this.$axios.CancelToken is undefined"
I can't see what I'm doing wrong and the docs appear to be telling me this works.
https://axios.nuxtjs.org/usage#cancel-token

This was due to the nuxtjs/axios package being too old.
The CancelToken only got added in 5.8.0

Amplify Flutter: How to connect to existing GraphQL endpoint

I'm implementing Amplify Flutter and want to connect it to our own custom GraphQL endpoint (i.e. non-AppSync). I am however having trouble getting it to work. The official documentation is not super-clear on this (at least not for those of us who are completely new to Amplify). What I have done:
In pubspec.yaml, I’ve added and installed the amplify_api package.
In main.dart, I’ve updated _configureAmplify() to add the AmplifyAPI() plugin.
In amplifyconfiguration.dart, I have manually added the following snippet:
"api": {
"plugins": {
"awsAPIPlugin": {
"xxxxxAPI": {
"endpointType": "GraphQL",
"endpoint": "http://xxxxxxxx.eba-fmuh2afu.eu-north-1.elasticbeanstalk.com/query",
"region": "[REGION]",
"authorizationType": "AMAZON_COGNITO_USER_POOLS"
}
}
}
}
But I keep getting the error "There is no API configured for this plugin with matching endpoint type." What am I doing wrong? (Note: I presume that I don't have to add any "region" value if I'm pointing to our own custom GraphQL endpoint).
I was able to fix this issue by closing the app and uninstalling it, then run again and log in to start fetching API

Error while deploying Aion dApp through frontend : fs.readFileSync is not a function

I was deploying my java contract to the Mastery network through the frontend by using a MERN stack app and came across the following error while compiling:
Module not found: Error: Can't resolve 'fs' in '/home/parina/Documents/aion-counter/node_modules/aion-web3-eth/src'
To rectify this, I added
node: {
fs: "empty"
},
to my webpack.config.js file.
After this, I was successfully able to compile my project and start the server but on opening the project in the browser, the contract was not deployed and I got the following error in the console:
TypeError: fs.readFileSync is not a function at Contract.deploy (index.js?60f4:244) at _callee$ (Main.js?1523:40) at tryCatch (runtime.js?280d:65) at Generator.invoke [as _invoke] (runtime.js?280d:303) at Generator.prototype.<computed> [as next] (runtime.js?280d:117) at step (Main.js?1523:9) at eval (Main.js?1523:9) at new Promise (<anonymous>) at eval (Main.js?1523:9) at deploy (Main.js?1523:19)
After searching on various forums, I found out that fs is not supposed to be used on the frontend and I was suggested alternatives to it. But it here it is being used by the Aion node modules and not directly and therefore I can’t seem to find the way around it.
As you mentioned since, fs is a server-side module, the file can be uploaded (through react or whatever is the clientside module) to the server and executed server-side and response returned to the client.
So I would suggest to get the encoded byte code of the jar along with the deployment arguments and set the transaction data field to the encoded data.
For example, assuming you are deploying the counter sample contract(https://docs.aion.network/docs/deploy-a-contract#section-example-script):
let data =

This can be your transaction object.
The issue got resolved here:
https://github.com/aionnetwork/aion_web3/issues/78#issuecomment-513938605
Since fs cannot be used on the client-side, I shifted the deployment function in my MERN dApp on the server-side while doing the rest of the interactions on the client-side.

How to create and call cloud code functions on parse-server?

I'm trying to run some very basic cloud code function on my parse-server and I get the same error every time: 141 Invalid function. I'm just adding a main.js file with my function in the cloud directory and trying to call it using Postman, but it looks like the file is not even called.
I've tried locally and on a docker, if the function exist or not I get the same result, and tried restarting the docker container after adding the code. I also tried adding a body to the request with parameters like master and functionName.
Here's my cloud code function (cloud/main.js):
Parse.Cloud.define('hello', function(req, res) {
return "function called";
});
Calling the function with a POST request on https://myurl/parse/functions/hello
and getting:
{
"code": 141,
"error": "Invalid function: \"hello\""
}
The response object has been removed from Parse Server Cloud Code post v3.0.0.
Your Cloud Code function should look like this...
Parse.Cloud.define("hello", async (request) => {
return "function called";
});
Please read the migration guide for more details on updating your cloud code to v3.0.0 or above.

WorkboxSW constructor throws error Undefined

In my service worker file, I am using this code:
importScripts("https://storage.googleapis.com/workbox-cdn/releases/3.0.0-beta.2/workbox-sw.js");
const workbox = new WorkboxSW();
But I am getting error Uncaught ReferenceError: WorkboxSW is not defined hence my service worker is not registering.
In Workbox v3, you won't normally explicitly construct a WorkboxSW instance. Instead, there's a workbox variable exposed in the global scope that provides the interface to the library.
Here's an example, excepted from the migration guide:
Previously in v2:
importScripts('<path to workbox-sw>/importScripts/workbox-sw.prod.v2.1.3.js');
const workbox = new WorkboxSW({
skipWaiting: true,
clientsClaim: true,
// etc.
});
workbox.router.registerRoute(...);
In v3, you just have to import the workbox-sw.js script, and a ready-to-use instance will be automatically available in the global namespace as workbox:
importScripts('<path to workbox-sw>/3.0.0/workbox-sw.js');
// workbox is implicitly created and ready for use.
workbox.routing.registerRoute(...);
I faced a similar issue but in my case, my sw was registering despite the error message. Adding type="javascript/worker" like this: <script type="javascript/worker" src="sw.js"></script> at my entry point, removed the error in dev tools.

gcloud deploy function error code 3

I'm doing the tutorial of basic fulfillment and conversation setup of api.ai tutorial to make a bot for facebook messenger, and when I try to deploy the function with the command:
gcloud beta functions deploy testBot --stage-bucket testbot-e9bc4.appspot.com --trigger-http
(where 'testBot' is the name of the project and 'testbot-e9bc4.appspot.com' is the bucket_name, I thought..)
It return the following error message:
ERROR: (gcloud.beta.functions.deploy) OperationError: code=3, message=Source code size exceeds the limit
I've searched but not found any answer, I don't know where is the error.
this is the JS file that appear in the tutorial:
/
HTTP Cloud Function.
#param {Object} req Cloud Function request context.
#param {Object} res Cloud Function response context.
*/
exports.helloHttp = function helloHttp (req, res) {
response = "This is a sample response from your webhook!" //Default response from the webhook to show it's working
res.setHeader('Content-Type', 'application/json'); //Requires application/json MIME type
res.send(JSON.stringify({ "speech": response, "displayText": response
//"speech" is the spoken version of the response, "displayText" is the visual version
}));
};
Make sure you are in the correct directory where your go code resides before executing gcloud beta functions deploy testBot --stage-bucket testbot-e9bc4.appspot.com --trigger-http command.
I was working in the express project. In my case, I mistakenly installed the #google/storage package in devDependencies instead of dependencies. I unable to notice as I tested the project in debug mode using mocha. So in debug, it is able to find that package in devDependencies but on deploy function, it tries to find in dependencies in package.json but unable to find there.
Open command prompt at the location where index.js was created and run the above gcloud command.
