Can't deploy nextJS to cf pages (stuck)

I’m trying to deploy this portunus-dev/portunus-ui (github.com) on the cf pages and I even followed all the steps mentioned here: Deploy a Next.js site · Cloudflare Pages docs

But I’m getting the following error:

Any help is appreciated.

Looks like you’re using Yarn 1 and Yarn 3 isn’t liking it. Can you try adding a YARN_VERSION environment variable with the value 1

@WalshyMVP
Oh thanks for pointing that out, don’t know how I missed that little detail.

Also, I was able to pass that error but now a ton of warnings, are they of any major concern?
