I've just taken over a project from a disgruntled developer who thinks he's the best thing since sliced bread.
The error
He swears his code was running on the last commit... although, I get problems in an async/await. I vaguely remember having similar problems when not supporting the right version of babel, but that was years back. The project is created with create-react-app.

You are passing a promise to the function, and promise is not a function. You should do instead: await f and not execute it by await f() since the promise just needs to be called and not to be executed.

all my test case are failing with above error
I changes my version, even tried to update the enzyme and dependencies but ended in failure
When running npm run build I'm getting Module not found error. The extension in the request is mandatory for it to be fully specified.
This is relating to a shared package I created using create-react-library. This lib is being referenced in a new project using the latest create-react-app.
I have created a config-overrides.js file setting fullySpecified to false but this does not seem to have any affect.
Any idea what I am missing?
Module not found: Error: Can't resolve './utils' in
'C:\Users\Bob\source\repos\my-react-app\node_modules#my-lib\shared\dist\services'
Did you mean 'utils.js'? BREAKING CHANGE: The request './utils' failed
to resolve only because it was resolved as fully specified (probably
because the origin is strict EcmaScript Module, e. g. a module with
javascript mimetype, a '.mjs' file, or a '.js' file where the
package.json contains '"type": "module"'). The extension in the
request is mandatory for it to be fully specified. Add the extension
to the request.

When I build my React web app it looks very different from the development mode. I use serve -s build to watch when the app is build. But also on my online Digitalocean server, it won't look the same as in development. So it probably has something to do with React or how it was build.
This is in development mode:
This is when it is build:
So it looks CSS or Javacript did not compile correctly.
This is my package.json

I Hope someone can help me with this. Thanks for all help!
you should add a .env file in your root and add:
REACT_APP_SC_DISABLE_SPEEDY=true
The Styled Components library uses something called the "Speedy mode" to inject styles on production. you can Google it for more info
I am having trouble getting a create-react-app 3.4.1 build running on iOS 10 safari. It runs fine in development (npm run), but after building it, accessing the site throws the following error in the console : SyntaxError: Invalid unicode escape in identifier: '\u2160'. (bitwise or character)
