Expected Behavior

The same tests didn't break when I ran them in my environment last week, and undici v7.1.0 appears to just be just released couple of days ago.

Thanks for reporting!

Can you provide steps to reproduce? We often need a reproducible example, e.g. some code that allows someone else to recreate your problem by just copying and pasting it. If it involves more than a couple of different file, create a new repository on GitHub and add a link to that.

I've never used enzyme, but this seems similar to enzymejs/enzyme#2524 (comment)

[jimmyzhen]

@mcollina I created a repo for you to reproduce the reported test error. Please let me know if you have any questions.

Your repository uses https://github.com/wojtekmaj/enzyme-adapter-react-17, which is archived and not maintained anymore. My guess is that old module does not support those globals (TextDecoder). I would recommend to update your dependencies.
