> 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.
