extends-post-css-plugins example doesn't work

[AndrejGajdos]

I tried this example with CRA v5, but it doesn't work. You can check sample repo here where I tried to use postcss-color-rgb. You can run the project, but the css file is not processed.

At first I tried craco 6.4.3, but I was getting this issue. When I replaced postcss with postOptions, I didn't get any errors, but the css is not processed. Then I came across this suggestion and tried both postcss and postOptions, but the css is still not processed.

Can confirm I am also dealing with this issue. It seems that craco is not correctly extending postcss.

Will post here if I manage to come up with a work around, please do the same 😃

Does someone has an update or a workaround for this? I am struggeling with the same problem and can't use postcss, always getting a compile failing error TypeError: plugin is not a function at new Promise ()).
I am using the latest craco version. I can't update any other versions, I am using:
"react-scripts": "^4.0.3"
"webpack": "4.44.2"

@AndrejGajdos I just tested your example repo with CRA 5 using the latest craco 7 alpha and it worked as expected. I tried changing the background color in the App.css file and it updated properly. Are you able to reproduce the issue using the latest alpha of craco 7?

@dbgordon09 is this still an issue for you as well?

@SophieAnn what version of craco are you using?
