      Work Description: robinp commented on pull request #7889: [BEAM-5381] Fix 
two issues with generating the pipeline plan for Go SDK
URL: https://github.com/apache/beam/pull/7889
 
 
   - Wrong id was returned for CoGBK expansions, so the expanded transform 
didn't end up in the subtransform of the parent Scope.
   - CoGBK inject node outputs need to include edge name as well, not just 
input node name, otherwise there's an output name collision (caught by Flink 
runner's consistency check).

> If the attached {{beam_dataflow_err.go}} pipeline is executed with the 
> {{dataflow}} runner, GCP reports the following error:
> {code}
> Step with name e5 already exists. Duplicates are not allowed.
> {code}
> Executing the pipeline in {{--dry_run}} mode shows that "e5" is indeed 
> duplicated.  If the CoGBK in the pipeline is not scoped, the duplication is 
> fixed.
