Thanks for this contribution! You will need to sign the CLA before I can merge this.

The core change LGTM. Can you fix up the dependencies to get the test CI to run?

[bryanhuhta]

I think you need to do a go mod tidy on this, as github.com/grpc-ecosystem/go-grpc-middleware is a direct dependency.

Also, we need to use github.com/grpc-ecosystem/go-grpc-middleware/v2 instead, to avoid other dependency conflicts with google.golang.org/grpc.

Should be good now!

[devgianlu]

Used the make target, should be good for real :)

[bryanhuhta]

Unfortunately the make target doesn't sync x/k6. See #142 (comment) for next steps to get CI to go green. I'll open a separate PR to improve the make target for the future.

I have signed the CLA, not sure why it displays both signed and pending.

@devgianlu I apologize for more book keeping requests, but it looks like github.com/grpc-ecosystem/go-grpc-middleware/[email protected] is requiring an update of github.com/stretchr/testify to v1.10.0 (formerly v1.9.0 was required by the project).

Would you be able to run go work sync inside ./x/k6?

After that, CI should go green and I can merge this 👍

[devgianlu]

Third time's the charm?

[devgianlu]

Synced github.com/grafana/pyroscope-go/godeltaprof/compat too

LGTM! Thanks for this contribution 🎉
