Angular 15: Webpack throws error if I require ES6 support in browserslist file

My browserslist file is
> 0.5%
last 2 versions
Firefox ESR
not dead
not IE 9-11
and when running ng build it throws a warning saying that ES5 output is not supported by the Angular CLI
so i added the following line to browserslist as this answer suggested:
supports es6-module
but then Webpack throws invalid version error (tp.0)
Log:

TypeError: Cannot read property 'length' of undefined - While deploying using hardhat

I am getting the following error while trying to deploy a Mock contract on the hardhat development chain.
I am following:
Learn Blockchain, Solidity, and Full Stack Web3 Development with JavaScript – 32-Hour Course by Patrick Collins on FreeCodeCamp YT channel
I got this error while I was at 10:48:53 of the above course. I tried almost every thing but nothing helped but I found where the problem was occurring.
Ques: Where do I think the problem is occurring? (12:26)
According to me the problem is at the line where we are trying to deploy the script and we are waiting for the promise to be returned.
Here is the error:

Here is the code snippet in which I am getting the error:
const { network } = require("hardhat");
const { developmentChains, DECIMALS, INITIAL_ANSWER } = require("../helper-hardhat-config");
module.exports = async ({ getNamedAccounts, deployments }) => {

const { deployer } = await getNamedAccounts();
const chainId = network.config.chainId;

});
log("Price Feed Mock deployed!");
log("==============================================");
}
}
module.exports.tags = ["all", "mocks"];
Please help me with this problem 🥹
I posted this question on Ethereum Stack Exchange but got no help.
System configuration: MacBook Air M1 2021 - Monterey 12.4, yarn: 1.22.18, Hardhat: 2.9.6

I got the answer from the MASTER himself, #PatrickAlphaC.
When we call await getNamedAccounts in the above code, hardhat looks for the length of the named accounts in our hardhat.config.js
We have to make sure that the property given below is in there!
namedAccounts: {
deployer: {
default: 0, // here this will by default take the first account as deployer
},
},
This solved my problem and I was HAPPY again!

Make sure you have await in getNamedAccount(). Also name must be correct.
Must have correct entry for named accounts as below:
namedAccounts: {
deployer: {
default: 0,
deployer
1: 0,
},
},

I was stuck for a while with this as well, and was also following this same course.
Cannot read properties of undefined (reading 'length')

Initially I was writing from scratch and kept getting this error and plus hardhat npm installation. I decided to test just in case the course code, so I cloned the repo and surprisingly was also struggling with npm install issues for hardhat and waffle.
npm ERR! code ERESOLVE
npm ERR! ERESOLVE unable to resolve dependency tree
npm ERR!
npm ERR! While resolving: hardhat-project#undefined

npm ERR! Fix the upstream dependency conflict, or retry

So fixing dependency hardhat-ethers by overriding it, fixed all issues for me, so try this:
"devDependencies": {
...
"#nomiclabs/hardhat-ethers": "npm:hardhat-deploy-ethers#^0.3.0-beta.13",
...
},
"overrides": {
"#nomiclabs/hardhat-waffle": {
"#nomiclabs/hardhat-ethers": "$#nomiclabs/hardhat-ethers"
}
}
I got solution from Installation advice breaks #nomiclabs/hardhat-waffle
Now, I noticed that you have already solved your problem, but I wanted to add my solution as well just in case if someone else is struggling with deploy being undefined in terminal. In my case namedAccounts and await getNamedAccount() was fine.

Can you help me to solve this error about json?

I'm trying to connect Firebase using node.js
I have following code in my json file.
const functions = require('firebase-functions');
const hmac_sha256= require ('crypto-js/hmac_sha256');
const request= require('request');
const admin= require('firebase-admin');
const service_Account= require('./service_account_key.json');
const firebaseConfig= json.parse(process.env.FIREBASE_CONFIG);
firebaseConfig.credential= admin.credential.cert("service_Account");
admin.initializeApp(firebaseConfig);
exports.getCustomToken = functions.https.onRequest((req,res)=>{
const accessToken= req.query.access_Token;
const FacebookAppSec= '72100b8d4ee21a85fc67d014f3b0c9fa';
const AppSecretProof= hmac_sha256(accessToken,FacebookAppSec);
//Validate token...
const uri='https://graph.accountkit.com/v1.1/me?access_Token=${accessToken}&App_Proof=${AppSecretProof}';
request({
url= uri,
json:true
},(error,fbresponse,data)=>{
if(error)
{
console.error('Access Token validation request failed\n',error);
res.status(400).send(error);
}
else if(data.error)
{
console.error('Invalid Access Token\n',
'access_Token=${accessToken}',
'App_Proof=${AppSecretProof}',data.error);
res.status(400).send(data);
}
else
{
admin.auth().createCustomToken(data.id)
.then(CustomToken => res.status(200).send(CustomToken))
.catch(error => {
console.error('Create Custom Token Failed.',error);
res.status(400).send(error);
})
}
})
})

I see many answers on stack overflow as well as on github, but nothing proceed. i have tried my best to solve it by myown also get help from online community but now posting this to all of you.

The output shows that ESLint is giving you this error message on line 19 of index.js:
19:9 error Parsing error: Shorthand property assignments are valid only in destructuring patterns
Line 19 is url= uri below:
request({
url= uri,
json:true
},(error,fbresponse,data)=>{
If you want to give values to properties in a JavaScript objects, you have to use : instead of =, just like you did with json:true.
request({
url: uri,
json:true
},(error,fbresponse,data)=>{

Getting error on gatsby build command: TypeError: Unexpected response from worker: undefined

I am getting this error when I run the command $ gatsby build on the terminal.
What gets my attention on this one is that it mentions jest-worker, and I don't see that module on my package.json. I see it only in the node_modules folder.
I already tried many things. Deleting node_modules, package_lock.json, npm cache clean --force and some other things.
I can't find these errors on the internet either.
If I keep scrolling down on the terminal, the error ends with this:

Gulp build formatError - gulp + harpjs + gulp-gh-page + node

I'm working on a project based on :
https://github.com/superhighfives/charliegleason.com
Everything was working so great, and now i have a problem when i try to build the project using gulp build ...
The link to the img of the term error:

The build process is the same that you can see in the link below. For the build part :
gulp.task('build', function (done) {
cp.exec('harp compile . dist', {stdio: 'inherit'})
.on('close', done)
});
If anybody have an idea about the way i can fix this ... ???
Thanks,
Q

I ran into the same error with a Gulp/Harp setup after installing nvm. I fixed it by re-installing Harp.js globally.
npm install -g harp
