Tried bumping up to newer nixpacks version, regenerating pnpm lock, not sure what else to do as this looks like an error within nixpacks.

Hmm that is strange. I was able to build with node 22 no problem. Can you please try kicking off another build. I wonder if it was a network problem.

I've tried redeploying 7+ times at this point. You can see that this same nixpack commit hash works in the 'Dash' service if you look at the environment, but it fails with the "API" and "App" ones.

Can you please try setting the nixpacks version to the last version that worked https://docs.railway.app/reference/config-as-code#nixpacks-version

The builds started to fail randomly from nixpacks. I hadn't updated the version I was on for at least a month when the builds started to fail from this error. I updated the version to see if that would help, but it hasn't.

Tried adding nixpacksVersion = "1.24.0" to the nixpacks and it fails still. Same error.

Nixpacks was updated automatically which looks to have changed something with your build. On your previous working deploy it was using node 21 instead of 22. I think downgrading nixpacks or setting node version to something not 22 should fix the build.
Alternatively the team can investigate the build failure more deeply on Monday.

Oh I am trying to just use LTS. I'll try removing nixpkgsArchive and see if that helps. I thought setting that to a hash would lock it in for the specific version on that commit.

Removing nixpkgsArchive worked. Not sure why it is trying to use 22. Hope this ticket helps you guys find something interesting!

Ahh that makes sense then. Nixpacks was updated to support node 22 and that must not be included in the archive you had set. Glad it is resolved!
