It looks like something isn't right with the dep.url in src/fetch.zig. Maybe not related but could be leading to this issue.

this is a temporary and objectively bad fix

[RossComputerGuy]

We get a bit more of a cleaner MissingNixHash error instead of just missing fields now. It doesn't say which one but now it's at least recognizing there's a problem.

[Sh4pe]

I've just tested the new main after #61 is merged against https://git.sr.ht/~leon_plickat/wayprompt. It works now. @Artturin please check if it is fixed.
