webpack: Cannot read property 'call' of undefined

Bug report

What is the current behavior?

There’s an issue report https://github.com/pmmmwh/react-refresh-webpack-plugin/issues/328 on react-refresh-webpack-plugin, and I happened to encounter it as well.

At fist glance it seems to be a bug over there, however, it might be a bug in webpack after I debug with a breakpoint.

Hence I’m reposting it here.

If the current behavior is a bug, please provide steps to reproduce.

See https://github.com/pmmmwh/react-refresh-webpack-plugin/issues/328#issuecomment-804797961 for the steps.

What is the expected behavior?

No error should happen.

I also noticed this issue, when using ModuleFederationPlugin and some specific settings for the splitChunks.

splitChunks.chunks -> should not be set or set to async (default) , anything else will cause the error mentioned splitChunks.maxSize -> should not be set, if this is set will cause the error mentioned

and It reproduces only when loading the remoteEntry on the host app. The main app does not appear to be affected.

Seeing this error in conjunction with Module Federation, though it most likely isn’t due to that alone.

Strange thing is I don’t recally seeing this on versions earlier than 5.27, but it is now constant.
