VS BuildBundlerMinifier compile errors in site.min.css Expect comma, found '/'

Question

I'm using Visual Studio 2019 for an ASP.net Core solution, and BuildBundlerMinfier is used to to bundle js and css files on build.

if I have something like this in my css files that I include in the bundleconfig.json:

rgb(26 179 232 / 15%)
rgb(60 64 67 / 30%)

when I try to build I'll get this kind of compile errors for site.min.css (bundler output file):

Expect comma, found '179'  
Expect comma, found '64'  
Expect comma, found '/'

and my only solution for now is to not use this bundler for css.

Here is the solution that's right for you:

rgba(26, 179, 232, 0.15)
rgba(60, 64, 67, 0.30)
