I have just upgraded from RN 0.63.3 to 0.67.2...and Im now receiving an error when I try to clean project in Android studio

If you look at the file path its referring to (node_modules\#react-native-community\cli-plugin-metro\node_modules\metro\src\Server.js:350)...this is the line of code where its unhappy
processRequest = (req, res, next) => {
this._processRequest(req, res, next).catch(next);
};
Upgrading node to latest version fixed the issue

In a React-native project, I want to setup unit testing, For this I am using Mocha and Chai. When I run command npm test it executes mocha __tests__/*.js internally. In test file my code is following:
import { expect } from 'chai';
import Adapter from 'enzyme-adapter-react-16';
import { RefundedEmd } from './RefundedEmd';
import React from 'react';
import renderer from 'react-test-renderer';
describe('App', () => {
it('renders correctly', () => {
renderer.create(<App />);
});
});
I get following error in console:
C:\Technical work\Lorex\slf-mobile-impl\__tests__\App-test.js:1

I tried to use vue2-google-maps and it worked well.
Suddenly my computer had stopped working and then I restarted my computer.
Then, strangely, 500-error comes out.
I reverted all codes associated with vue2-google-maps then my project works well.
Even though when I import vue2-google-maps then It occurs 500-error. :(
App.js
import * as VueGoogleMaps from 'vue2-google-maps';
It was working well but now cause of the unknown reason it has been broken...
Here is my console shows error.

Is it possible that project that worked well could cause 500-error for no reason?
Environment: Ubuntu 18.04, npm v6.9.0, node v12.6.0
I have found how to handle ssr.
App.js
if (process.browser) {
const VueGoogleMaps = require('vue2-google-maps');
Vue.use(VueGoogleMaps, {
load: {
key: 'myKey',
libraries: 'places',
},
});
}
Instead of using import, I used require when it is client rendering.
I will be happy if it helped you. :D
I have a flaky end-to-end test that uses Detox and Mocha.
The Mocha test runner allows for multiple retries. I tried using the recommended Mocha syntax:
// auth.spec.js
describe('App authentication', () => {
this.retries(2);
it('should have a login screen', async () => {
await expect(element(by.id('LoginScreenView'))).toBeVisible();
});
});
However, it appears this is an empty object ({}) and does not have a retries function when running Detox with Mocha as the test runner.
It generates the following error:
node_modules/.bin/mocha __e2e__ --opts __e2e__/config/mocha.opts --
configuration ios.sim.debug --grep :android: --invert --artifacts-location "__e2e__/artifacts/ios.sim.debug.2018-10-17 22-51-12Z"

Is there a way to automatically retry failed tests in Detox?
this in mocha can't work with arrow function, so must change it into ordinary one
// auth.spec.js
describe('App authentication', function () { // change it
this.retries(2);
It is not recommended best practice to use in Mocha
Ref:
https://mochajs.org/#arrow-functions
Hope it helps

Found a fix
This issue is realated to
https://github.com/electron-userland/electron-builder/issues/2986
Looks like the issue is not present in version or electron builder before 20.8.1
If you are using node version 7.x or lower, update your node installation.
Async is not supported until node version 8.
