Error when toolchain override: "Dependency is not of a valid type: element 2 of nativeBuildInputs for cargo-package-deps"

[zmrocze]

Describe the bug

I cannot override the toolchain, packages build without trying to override. Not sure which component is resposnbe for the error - whether its crane, rust-overlays or sth I defined.

Reproduction

nix run github:zmrocze/midi-mapper/bug-repro#midi_printer --show-trace

results in

warning: Git tree '/home/zmrocze/code/rust/midi-mapper' is dirty

Hi @zmrocze I think the version of crane locked by flake.lock is pretty out of date. Building with a newer version does not have this issue (the build still fails but it's the actual cargo invocation and not the Nix evaluation):

nix build github:zmrocze/midi-mapper/bug-repro#midi_printer --show-trace --override-input crane github:ipetkov/crane

I'd recommend running nix flake update and investigating your project build configs further; hope this helps!
