Thanks for reaching out! There's actually a bug in the exporters that I'm working on fixing that loads grpc too early and causes this error message to be logged. (open-telemetry/opentelemetry-js#4151). It also interferes with the grpc instrumentation and causes telemetry to not be generated. I'll close this as a dupliacte in favor of the issue in the core repo for now.

Please let me know if you think this is a mistake, then I'll re-open this issue. 🙂
