Any ideas?

I am surprised this isn't set. But if you set this variable on the derivation in question, then also an env var with that name should be set.

I think I was able to workaround it by setting CARGO_CRATE_NAME in Cargo.nix.

You should be able to reproduce the problem with just:

[dependencies]
opentelemetry-tide = "0.6"

Hitting this problem for CARGO_PKG_LICENSE as required by built, fwiw.
