Why can't ffmpeg worker.js be loaded via blob url?

[hellohejinyu]

Because my project will eventually upload resource files to a storage bucket and host them under another domain name. So in order to solve the cors problem of the worker, I used pnpm patch to modify the code of @ffmpeg/ffmpeg and tried to load worker.js through the form of blob url.

But if I switch to blob url, it will fail, and there will be no output in the console, as if nothing happened.

Maybe it's because the import in worker.js can't be resolved properly when I import it through the blob url?
