I'm using socket.io-client in my React js web app. It compiles without error, but when I try to open the development server (localhost:3000) I get the following error:

In this project where the error is being thrown, here is a list of the relevant packages and their versions:

• @testing-library/jest-dom@5.14.1
• @testing-library/react@11.2.7
• @testing-library/user-event@12.8.3
• react-dom@17.0.2
• react-scripts@4.0.3
• react@17.0.2
• socket.io-client@4.3.1

Webpack Version: 4.44.2

Threads like this one suggest that this is some sort of issue with mixing import and module.exports in ES6, but I definitely don't want to modify the socket.io-client module.

In a previous React project, where the module works, here is a list of the relevant packages and their versions:

• @testing-library/jest-dom@4.2.4
• @testing-library/react@9.5.0
• @testing-library/user-event@7.2.1
• react-scripts@3.4.4
• react@16.14.0
• socket.io-client@4.1.2

Webpack Version: 4.42.0

I've played around a little bit with different versions of socket.io-client and react to try to get it working, but to no avail...
