Because importModule run code on Node.js side (in remix-loader), so you got such problem, we can't solve it here, sorry, you can look at mini-css-extract-plugin logic (we do the same logic)

[alexander-akait]

Als you can try to set:

{
            loader: 'css-loader',
            options: { modules: true, url: false },
          },

But urls will not be resolved (but no errors)
