The `tonic 0.14` has much improved error messages: * https://github.com/hyperium/tonic/pull/2403 This repositority was updated to `tonic 0.14` a while back: * https://github.com/open-telemetry/opentelemetry-rust/pull/3093 I would really appreciate a new release of the `opentelemetry` crate to crates.io 🙏
