v20.14.0

The reproduction repository contains two tests. One is firing an XHR request, and the other one is firing an XHR request with a FormData body.

If you use v2.4.3, the tests will pass. When using version 2.4.4+ it fails.

The XHR request with FormData never resolves. This has worked fine previously, but since version 2.4.4, it does not work anymore.

It is possible to upload file / FormData with msw using XMLHttpRequest.

I am also encountering this, but only on linux. On my Mac it works fine. What OS are you using?

roastnewt commented 1 week ago

Windows. And also in our Ubuntu build/test pipeline

Getting same only on Linux (windows and mac work fine). Has there been any work started on this?

I had a similar issue and it worked only on Node V18. I tried with V20, V21, and V22, all of them failed the tests.

mswjs / msw
