How Do We Reproduce?

upgrade to webpack5

I'm getting the same error:

The last error seems similar to webpack/webpack#10790

[Paul Whipp]

Same issue with webpack 5.9.0. If I kill the webpack server, the error disappears on restarting it. It reappears when I subsequently modify the file reported in the error.

The changes display correctly in spite of the error.

Having a similar problem - using optimization.runtimeChunk works for me.

Same issue with webpack 5.9.17
On version 4.46.0 HMR works fine.

Also you can try target - web, in newly versions.

Having the same issue.

webpack 5.37.0
webpack-dev-middleware 4.2.0
webpack-hot-middleware 2.25.0
browser-sync 2.26.14
mini-css-extract-plugin 1.6.0

Using webpack dev and hot middleware through a browserSync instance.

I get the below error on a JS or SASS change, and no patching happens:

On any try to patch JS or SASS:

Same result when replacing mini-css-extract-plugin with style-loader.

For JS, it works on the second change. The error only shows for the first update.
