> We have a {+}Java{+}, {+}streaming{+}, pipeline that consumes messages from Kafka and ingests them into BigQuery. We run this pipeline in Dataflow.
> Recently, we enabled the `.withDynamicRead()` option in our KafkaIO source to be able to auto-discover new partitions.
> As a result, the pipeline won't load in Dataflow with the following (not very informative) error:
> {noformat}
> "Workflow failed. Causes: Internal Issue (fc4aaa0289f1f666): 62242584:26". 
> {noformat}
> This error happens before the actual job graph can be generated.
> Google Support provided us with an internal Dataflow log message that can help to narrow the problem:
> {noformat}
> "invalid_argument: Duplicate side input name.  Side input names must be unique."
> {noformat}
> Some important pieces of information:
>  * The error only happens if the destination sink is BigQueryIO. We have tested it by replacing BigQueryIO with TextIO and it works OK.
>  * The error doesn't happen if pipeline is run by DirectRunner; only DataflowRunner.
>  * We have reproduced this error in Beam SDK versions 2.34 and 2.35.
>  
> I've written a small pipeline that reproduces the error. Please find it attached in the ticket [^Main.java].
