Google Cloud Functions

Go Environment

$ go version: 1.22.3
$ go env

Code

e.g.

http.DefaultTransport = otelhttp.NewTransport(&http.Transport{...})

identityClient, err := identitytoolkit.NewService(
		ctx,
		option.WithAPIKey(cfg.FirebaseAPIKey),
		option.WithGRPCDialOption(
			grpc.WithStatsHandler(otelgrpc.NewClientHandler()),
		),
	)

Expected behavior

Construction does not panic

Actual behavior

Panic

Screenshots

Additional context

Modifying the global http.DefaultTransport (e.g. to wrap an opentelemetry http roundtripper with new defaults) results in a panic when the client constructor tries to clone an expected *http.Transport. Is there a way to bypass the call when using grpc?
