What happened?

BigQueryIO has a bug where Write cannot be performed using .withAutoSharding() or .withNumShards(n) where n = 0 on DataflowRunner with unbounded data.

Setting .withNumShards(n) where n > 1 and disabling autosharding

This issue affects ALL streaming python pipelines run on Dataflow with cross language transform BigQueryStorageWriteApiSchemaTransform
