Production build does not work

[Schiavi]

Hello,

I'm having problems generating a Production version. I've copied the CRACO configs from this repo. Any ideas on what's happening?

Dev(yarn start) works normally. But when I try to generate a production build:

Here's the code in the error:

import { css } from 'linaria'

import { rem } from '../../utils/css'

export const cxMain = css`
  display: grid;
  grid-template-columns: 300px 1fr;
  grid-template-rows: calc(100vh - ${rem(80)});
`

Sorry for long answer.
@Schiavi is it working if you try to do the same inside this repo? Which version of react scripts are you using? Do you have any other craco transformations inside your project.
I've tried to do the kind of the same in this repo and it worked.
