error[E0080]: evaluation of constant value failed

Describe the bug
Seeing these errors since last night. No changes on our side, this just started failing. Probably some unpinned dependency.

Any ideas?

I see this is failing in your repo as well ~ on the latest PR: #3671

CI Run: https://app.circleci.com/pipelines/github/apollographql/router/14826/workflows/52095d11-eba9-4d24-b41a-2283854e0640/jobs/97028

Seems to be due to Rust 1.72.0 pinning toolchain to 1.71.1 fixed the issue for us.

Thanks for opening this! I'll close this as a duplicate of #3684, which has a reproduction.
