Why is this PR CI failing?

I want to imrove error message for rustPlatform. Any ideas why the CI is failing? rustPlatform: Improve Cargo.lock mismatch error message by MrQubo · Pull Request #531979 · NixOS/nixpkgs · GitHub

Might not having anything to do with that PR. Could be something else wrong on staging at the time it branched off. If so, and it’s been fixed since, rebasing the PR might fix it.

The eval error appears to have been fixed in weblate: make pythonRelaxDeps more robust by dotlambda · Pull Request #532103 · NixOS/nixpkgs · GitHub which is currently merged into master.

Thanks! Indeed, I just had to rebase.
