instrumentation-grpc doesn't seem to get initialized with --require @opentelemetry/auto-instrumentations-node/register

[dudo]

What happened?

grpc (and others, but I'm especially concerned with grpc) traces aren't being emitted. Calls are successful, but no trace is emitted, and no context (or baggage) is propagated. Incoming http and dns traces are present, so it seems isolated some instrumentation.

I'm using modules and passing --require as an argument to node.

Here's a repo reproducing the problem:

https://github.com/gitops-ci-cd/acme-node/blob/main/package.json#L7

Simply run

docker compose watch

then visit http://localhost:8080/api/v1/hello.

I see hooks for http and dns, but none for grpc (or even express, which I'm using)
