Describe the issue

I use the bootstrap-5.1.3 Version in my Laravel, VueJS Project for a while. Now only if I do npm run prod, I got this error:

ERROR in ./resources/sass/app.scss Module build failed (from ./node_modules/mini-css-extract-plugin/dist/loader.js): ModuleBuildError: Module build failed (from ./node_modules/postcss-loader/dist/cjs.js): JisonLexerError: Lexical error on line 1: Unrecognized text.

Erroneous area: 1: none - 1px ^..^ at /Users/snitch/Work/DDV/Auktio_2/auktio2/resources/sass/app.scss:3801:3

But dev build works fine. I have googled and found solutions but for bootstrap 4.3 an old version. Does anyone know where I can find a part of the scss where I can fix this? app.scss:3801:3, should I count all lines in my includes to get to that line?

Any suggestions are welcome, maybe I found a Bug in 5.1.3, I did not know.

Kind Regards, Marcel

Can't help without a reproducible test case that shows this is coming from Bootstrap. This seems like an issue in your implementation.

OK what should I post here to find a solution for this? Ihave a Laravel APP and I use laravel-mix, bootstrap-5.1.3 and SCSS postcss setup.

I think I have found the bug. So, in the .modal-header class in the _modal.scss file, there is the following include:

.modal-header {
...
@include border-top-radius($modal-content-inner-border-radius);
...

This line uses the @mixin border-top-radius($radius: $border-radius) if $enable-rounded is true. The output of this line is:

.modal-header {
  display: flex;
  flex-shrink: 0;
  align-items: center;
  justify-content: space-between;
  padding: 2.5rem 2.5rem;
  border-bottom: 1px solid #333333;
  border-top-left-radius: calc(none - 1px);
  border-top-right-radius: calc(none - 1px);
}

and the none will break my prod build. After looking at the scss files, there is the function valid-radius() but I did not know how to modify it to prevent this error in the future.

Any Ideas?

or it is the default variable -> $modal-content-border-radius: none; ?? in _variables.scss? I set to 0px and now the error is gone.
