Webpack 5.1.3 chunk.files.delete

[codebygs]

I'm getting this error when running production build with with FixStyleOnlyEntriesPlugin. Should I provide some more info?

The best you can do is create a demo repository with a minimal reproducible example.

Webpack 5 support is still crude. Most of people (as I do) still uses webpack 4.

Also, there is no specific tests for webpack 5 yet, since I had issues trying to use multiple versions of webpack on the tests.

I was able to get around it by changing the file name [contenthash] to some other value.
(ex: [hash])

@fqborges here is the repo: https://github.com/thesame-/webpack-fix-style-only-entries-webpack-5-issue

Webpack 5 will use a real hash of the file content when using [contenthash] now. Before it "only" used a hash of the internal structure. This can be positive impact on long term caching when only comments are changed or variables are renamed. These changes are not visible after minimizing.

This seems to be the cause of issue. devmgn's solution worked for now.

@Locheed Can you elaborate please? I'm new to Webpack. Will changing contenthash to hash work? Does it mean every filename will change on each build?

@thesame- I'm facing the same issue, and yes, using [hash] every filename will change on each build.
