Turn your JavaScript with [async functions] into ES6 generators so they can be used in modern browsers or in node.js (v0.12 or newer). Async functions are an exciting new proposed addition to JavaScript. The v8 team is [hard at work] getting it right, which means it could appear in future versions of node.js. However if you’re impatient like me, then you probably just can’t wait to get rid of your promise triangles and [callback hell] You can use [Babel] to accomplish this, but async-to-gen is a faster, simpler, zero-configuration alternative with minimal dependencies for super-fast npm install and transform time. Also, async-to-gen provides support for [async generators] which return Async Iterators, a great syntax and primitive for producing and operating on streams of data.

QUESTION
Element type is invalid: expected a string (for built-in components) or a class/function (for composite components) but got: null. Check the render method of TransitionGroup.
To be very specific, this issue only occurs when I use material-ui and import any of it's component. I can't provide specific steps to reproduce this as it seems to be a webpack config or a babel config and this is a very generic one. Also, there are bunch of others who experienced this issue already and I've tried many solutions with no success. That's why I decided that maybe the stack overflow community can shed some light.
So first, I'm 100% accurate that the issue is using @material-ui. In my project I tried importing just a Button like so
import Button from '@material-ui/core/Button'
And using it like:
...ANSWER
Answered 2020-Jul-12 at 09:59The only thing that sticks out to me is the fact that you configured babel with "commonjs" in the first preset. Try changing it to 'auto' or es6 modules.
The difference is that in commonjs you should import with const a = require('some-module')
And in es6 it's: import a from 'some-module'
You can test if this is the case by changing your import to:
const Button = require('@material-ui/core/Button')
or
const Button = require('@material-ui/core/Button').default
If it works, try removing the "modules" from the first preset or change it to "auto" https://babeljs.io/docs/en/babel-preset-env#modules
QUESTION
I've been trying to run my nuxt app in docker and the build seem to work for the most part other than it keep missing core.js dependencie. I've tried adding core-js manually, babel, tried to run the suggested install command in the error, but to no help.
Dockerfile:
...ANSWER
Answered 2020-Jun-22 at 15:38This had nothing to do with docker. I'm not sure how, but at some point reinstalling all the node modules installed the wrong core-js version.
Installing "core-js": "^2" seems to have solved it for now. Perhaps upgrading nuxt version would help too.

Answered 2020-Apr-30 at 18:35I have managed to fix it by adding "esModuleInterop": true to tsconfig.json.

Emit __importStar and __importDefault helpers for runtime babel ecosystem compatibility and enable --allowSyntheticDefaultImports for typesystem compatibility.
Which means nothing to me, but a bit more information here:
