Gatsby-core-utils not compatible with node 16?

I have a monorepo with multiple sites. Both Gatsby sites and a few Next JS sites.
Yesterday all builds started failing because of the update concerning framework detection and yarn, then it was fixed and most of the sites now build successfully.

Now another error has surfaced that wasn’t there before the update:

My Gatsby sites are using Gatsby v4 and like I said all built fine before the update.

Did you try upgrading to Node 18: Manage build dependencies | Netlify Docs?
