The service worker and `main.dart.js` need to be fetched from the root of your web server. If your web server's root is `http://localhost:9090`, then those files are supposed to come...

Bottom line is: some code is trying to download these files from the wrong path (with `/product/` in it). We need to find out where and why that is. @ditman...

Thanks for the detailed report, @Cotspheer! I was able to reproduce your issue. Some part of DDC (or JS code generated by the flutter tool, I'm not sure yet) gets...

And if you don't mind, could you please file a new issue with all the details that you shared?

FWIW, I found where the problematic code is being generated: https://github.com/dart-lang/build/blob/c88db16df8eab435a0ee74ecba65c39beda0a9e1/build_web_compilers/lib/src/dev_compiler_bootstrap.dart#L495-L504

I'll do a git bisect to find out which commit started the problem. I'm trying to find an old commit that's "good". I went as far back as November, and...

`git bisect` led to this PR: https://github.com/flutter/engine/pull/36851 Looking at the PR, it seems like this line is the culprit: https://github.com/flutter/engine/pull/36851/files#diff-fed47f409f6a27a39fe7b0e6b3ebbceb645d295259e350614afeb8c0a3eecae2R636 We basically always set `flutter_prebuilt_dart_sdk` to true for the wasm...

@whesse I suggest we keep this issue since it has more details. The other issue contains some outdated information, and the PR https://github.com/flutter/engine/pull/36926 did fix part of the issue, but...
