How can I run `chromiumDev`?

I want to run something in the upcoming Chromium 108. Luckily, chromiumDev was recently updated to 108. However, for some reason, I can’t seem to run it:

$ nix shell nixpkgs#chromiumDev
error: builder for '/nix/store/qzgg6zbd54v14xqhvgm96zjrw0has4s1-chromium-unwrapped-108.0.5327.0.drv' failed with exit code 1;

I get a similar error when adding it to my NixOS config. I am using NixOS unstable.

Is this an issue that I can fix, or is there something wrong in nixpkgs?

Yes, the package seems to be broken and needs fixing.
