federation runtime vue 3 remotes with getPublicPath generates double calls (one with wrong public path)

[WeetA34]

Describe the bug

Hello,

I use federation runtime to dynamically import vue 3 remotes with getPublicPath.
some css, vendors assets are called twice:

• once with the proper public path retrieved through the getPublicPath function
• once with the consumer url which returns in my case the root html.

you can see screenshots in the repro project README.

It doesn't always generate an issue as one of the two calls succeeds.

I don't have this behavior if I replace getPublicPath by a static publicPath.

Thank you

+1, seeing the same issue as well (with React, although that doesn't really matter here)

hmm seems like a legit issue. Will check the source code.
You can try setting public path to auto?

[WeetA34]

Hello Zack,
i'll test that.
thx

[WeetA34]

Hello Zack,
It seems to be ok without getPublicPath and config.output.publicPath set to 'auto' instead.
Thank you

[WeetA34]

Hello again,
I moved to @module-federation/rsbuild-plugin.
publicPath='auto' by default
It works fine

[ScriptedAlchemy]

Perfect

The wrong css asset is loaded by producer's miniCss runtime . It will use publicPath + assetUrl as final url .

And the producer not set specific publicPath , so it will call twice .

I am having the exact issue as the original poster describes, but when using RsBuild.

I used the workaround mentioned of setting config.output.publicPath, but I am setting it to a specific URL (not 'auto') and it builds the mf-manifest.json with publicPath: '/' which is not what I expect. Does config.output.publicPath not work with RsBuild?
