   The Exception triggers on this snippet:
   ```
   import apache_beam as beam
   from apache_beam.runners.direct.direct_runner import DirectRunner
   from apache_beam.options.pipeline_options import DirectOptions, PipelineOptions
   
   
   if __name__ == '__main__':
       pipeline_options = PipelineOptions()
   
       runner = DirectRunner()
       
       # Tried passing those to PipelineOptions as well, same result
       pipeline_options.view_as(DirectOptions).direct_running_mode = 'multi_threading'
       pipeline_options.view_as(DirectOptions).direct_num_workers = 0
   
       with beam.Pipeline(runner=runner, options=pipeline_options) as p:
           inputs = p | 'Create' >> beam.Create([{'foo': 'bar'}, {'spam': 'eggs'}])```
