I had on my project npm with verison 8.9.4 then I updated it to 14.18.0 and it works fine for me locally. But when I deployed my code on test environment I see that color doesn't work.

In code it looks like:

  color: var(--indigo)

With npm 8.9.4 in browser it looks like the same, but with npm 14.18.0 I see that in browser it looks like color: var(indigo);. Why 2 dashes disappeared?

Also I have scss preprocessor on my project, but this color also use in simple css files and it doesn't work around the project.
