I am surprised this bug has been present for so long!

Released a fix in 6.1.2.

Hi @Siilwyn and @thecrypticace ,

This was the dependency that caused this issue: https://github.com/NMFR/optimize-css-assets-webpack-plugin/issues/168 It’s fixed in 5.0.8 after updating to that dependency to that version, the problem was resolved.

@zfeher @dave105010 you are not using laravel-mix right? If you could provide an example using just webpack (as minimal as possible) that would help me out a ton!

Edit: Cleaned up the thread by hiding some comments which provide no new info, please read the posted replies so far before posting.

Hi Siilwyn,

No, we are on Rails 6 framework so not using laravel-mix. This was fixed after updating the dependencies for me. There was a bug on either this or on something else. They released an update a day later. I can’t remember the details but updating things fixed this for me.

After quite a bit of digging I found the error I was getting was due to RTLCSS control directives in an included SCSS file. Once I removed these the build succeeded without issue.
