Property 'getNetworkId' does not exist on type 'never' Typescript

I'm currently working with the cardano serialization library to code crypto transactions in typescript. I'm referencing a wallet connector template that has example code for transactions but is all written in Javascript. So in translating it over I've received a number of syntax errors that have generally been easy to resolve until now. I have a number of ts(2532) errors (Object is possibly 'undefined' that are solved through '?' chaining, I know that's not my best solution but for now I'm trying to get it error free first. When I utilize a ? operator chain though I then get the property does not exist on type 'never' error in the following code
getNetworkId = async () => {
try {
const networkId = await this?.API?.getNetworkId()
this.setState({ networkId })
} catch (err) {
console.log(err)
} }

Custom backend parse body in a better way

So I'm creating a custom backend (build on top of the http module) for fun. But I stumbled upon a problem with getting/parsing the body. I have solved it, but it still isn't what I am looking for. This is what I have now:
this.body = new Promise((resolve, reject) => {
let _d;
req.on('data', (chunk) => {
_d += chunk;
});
req.on('end', () => {
if(_d === undefined) return resolve(null);
resolve(JSON.parse(_d.replace('undefined', '')));
});
req.on('error', (err) => {
reject(err);
});
});
I have tried this without using promises but then the body will be undefined. Every time I want to access body I have to do this:
let body = req.body.then(value => {return value});
Is there a better way to do this.
Thank you for your time.

How can I pass data from one api endpoint to the other api endpoint in reactjs

I am working on an react app. This has to api endpoint /dispensing and /overview from dispensing we get some data that need to be passed to /overview endpoint when component mounts show that when user logged in it should show some data.
For that I am fetching the data from /dispensing and store it redux store and inside the component I passed it to /overview but it shows error that values is not defined but it is available in when I console.log.
And when I make refresh after that it works fine. I have no idea why.

how to sign bitcoin psbt with ledger?

I'm trying to sign a Psbt transaction from bitcoinjs-lib following what I found here:
https://github.com/helperbit/helperbit-wallet/blob/master/app/components/dashboard.wallet/bitcoin.service/ledger.ts
I've checked that the compressed publicKey both from ledger, and the one from bitcoinjsLib returned the same value.
I could sign it with the bitcoinjs-lib ECPair, but when I tries to sign it using ledger, it is always invalid.
Can someone helps me point out where did I made a mistake?
These variables is already mentioned in the code below, but for clarity purpose:
- mnemonics:

Ooof, finally got it working.
My mistake was I was trying to sign a p2sh-p2ms, By following a reference on how to sign a p2sh-p2wsh-p2ms.
And, also, that missing last 2 bit (01), which I think represent SIGHASH_ALL caused an error when I try to decode the signature.
this is my finalized working example.

My guess is you have a space in the string passed to toByteArray function. This function doesn't trim input. Also doesn't check if input's length is even.

Mocha pass different parameters to each test file

I have a test file with a single describe that I want to run it twice but each time I want to pass different parameters into it.
My code looks like that:
MochaRunner.js
'use strict';
const fs = require('fs');
const path = require('path');
const Mocha = require('mocha');
const uuidv1 = require('uuid/v1');
class MochaRunner {
/**
* #param {Object} options
*/
constructor(options = {}) {
this._tmps = [];
this._mocha = new Mocha(options);
}
/**
* Run tests
* #param {Array} tests
* #returns {Promise}
*/
run(tests) {
return new Promise((resolve, reject) => {
const Config = require('../config').create();
let counter = 0;
tests.forEach(test => {
const testDir = path.dirname(test.testPath);
const tmpTest = path.join(testDir,`${uuidv1()}.spec.js`);
fs.writeFileSync(tmpTest, fs.readFileSync(test.testPath));
this._tmps.push(tmpTest);
this._mocha.addFile(tmpTest);
Config.setOptions('var ' + counter++);
});
this._mocha.run((err) => {
return err ? reject(err) : resolve();
});
}).catch(() => {
return this.cleanup();
});
}
/**
* Get mocha instance
* #returns {Mocha}
*/
getMocha() {
return this._mocha;
}
/**
* Remove tmp test files
* #returns {Promise}
*/
cleanup() {
this._tmps.forEach(tmpTest => {
fs.unlinkSync(tmpTest);
});
return Promise.resolve();
}
}
module.exports = MochaRunner;
Config.js
class Config {
constructor() {
this.options = {};
}
setOptions(options){
this.options = options;
}
}
module.exports = {
_instance: null,
create: function(){
if (this._instance){
return this._instance;
}
this._instance= new Config();
return this._instance;
}
};
test.e2e.test.js
const chai = require('chai');
const Config = require('./config').create();
const assertionStyles = {
assert: chai.assert,
expect: chai.expect,
should: chai.should,
};
setImmediate(async () => {
describe('describe blah blha', function () {
console.log(Config.options);
it('test case', function () {
assertionStyles.expect(true).to.be.true;
});
});
run();
});
I do this when I want to run the above code:
let tests = ['test.e2e.test.js', 'test.e2e.test.js'];
let mocha = new MochaRunner({});
await mochaRunner.run(tests).then(() => {
mochaRunner.cleanup();
});
In the above example, I want to pass different data when the test will run for second time.
For example, I want the first file read the param from Config with the value:
'var 0'
and the second file read the param with the value:
'var 1'
Any ideas please?
Any help would be greatly appreciated!
