P2 Description
I tried to run wordcount example in go https://beam.apache.org/get-started/quickstart-go/
It worked fine in dev but when I try to run it on GCP dataflow, I got '"v1.proto" is already registered' error and job crashes.
It seems proto definition here is using very generic package name "v1" which I suspect is a cause of issue
https://github.com/apache/beam/blob/v2.28.0/sdks/go/pkg/beam/io/pubsubio/v1/v1.proto
Here is log in GCP
