Upgrading react-scripts to 4.x.x breaks my app

I have been developing a frontend app using React (v16.44.0, cannot upgrade to v17 yet due to a dependency), react-scripts v3.4.4, Typescript (v3.9.9) and React-Bootstrap (v1.5.1) for a few months and all is going well.

However, react-scripts have been updated recently to a v4, and upgrading breaks the whole app. I am concerned with securities issues with react-scripts v3. I also would like to upgrade Typescript to v4+, there seem to be an incompatibility btw Typescript 4 and react-scripts 3 related to eslint. Various deprecation warnings are also stacking up.

When I enable react-scripts v4.0.3, run npm start to launch the development server, Firefox (v78.8) throws:

"ReferenceError: SharedArrayBuffer is not defined" in "node_modules/webidl-conversions/lib/index.js:347".

Apparently webidl-conversions is required by bootstrap. I have searched about the SharedArrayBuffer issue, apparently it requires enabling additional headers, but I could not find how to add them using the npm start webserver.

[Edit: upgraded Firefox to v86, still have the issue but I have not tried to configure it yet.]

If I try with Chrome (v89), I have:

"TypeError: Cannot convert undefined or null to object" on "node_modules/whatwg-url/dist/utils.js:48"

which also seem to be required by Bootstrap.

I do not have a dependency on Bootstrap per se, I use the react-bootstrap implementation. However, I use bootstrap-scss for the (S)CSS part.

I can upload full stack traces if needed. Here is my package.json:

It's hard to tell exactly without your full package.json, but it seems that it's not related to the update of react-scripts itself, but instead probably an updgrade on another library that you are depending on that uses SharedArrayBuffer which is not supported in Firefox v78

Edit: OP found out that the problematic package was react-sketch

As per the other error, it seems to be related, but don't know exactly why it happens. Anyhow, found this issue in their Github page and one suggestion is to upgrade jsdom to version >=16.3 (if you are using it)

Did you apply each migration described in the changelog?

They also suggest you delete node_modules if you break your app when updating from 3.4 to 4.

NOTE: You may need to delete your node_modules folder and reinstall your dependencies by running yarn (or npm install) if you encounter errors after upgrading.

Try deleting it and running npm install

You can download Bootstrap CSS files manually and save them in project files.

Try:

Deleting your node_modules and package-lock.json

// This normally fixes my issue when going back to old react projects
npm cache clean --force 

run npm install

run npm run start
