BUG
What is the current behavior?
Entrypoint undefined = index.html
and
Entrypoint undefined = extract-text-webpack-plugin-output-filename
If the current behavior is a bug, please provide the steps to reproduce.
In webpack production mode with HtmlWebpackPlugin and ExtractTextWebpackPlugin
What is the expected behavior?
Have no errors
The error does’t affect the last output file, but it log lots of info in console.
Does the features about html entrypoint and css entrypoint working in progress throw the error ?
I faced the same issue of having a style only entry (css/sass/less) generating an extra .js file, and ended up creating a webpack plugin to remove the js file from the compilation.
I published it on npm as webpack-fix-style-only-entries. You can find the source code on https://github.com/fqborges/webpack-fix-style-only-entries.
🙂 shamelessly promoting my package 🙂
