Unable to override Request User-Agent using metadata

[zadamz]

Hello All,

Each client in our system has unique user-agent assigned to them.
We have a service that validates the request based on value set in "User-Agent" header/metadata in request.

I have tried to set the metadata in request using --metadata-file=mymetadata.json.

But server always receives User-Agent as "grpc-go/1.45.0". No matter what I set.

Is there any other way to set the UserAgent or am I missing some step?

Do point me to any reference/documentation I may have missed.

Thanks and Regards,
Adam
