-----------------------------------

             Summary: Can't use action with add_value_provider_argument()
                 Key: BEAM-10041
                 URL: https://issues.apache.org/jira/browse/BEAM-10041
             Project: Beam
          Issue Type: Bug
          Components: sdk-py-core
    Affects Versions: 2.20.0
         Environment: Apache Beam 2.20.0 (the GCP variant).
Python 3.6.9
Ubuntu 18.04

            Reporter: Daniel Gomes


The following code:
{code:java}
from __future__ import absolute_import
from apache_beam.options.pipeline_options import PipelineOptions
class UserOptions(PipelineOptions):
    @classmethod
    def _add_argparse_args(cls, _parser):
        _parser.add_value_provider_argument('--debug', action='store_true')
if __name__ == '__main__':
    pipeline_options = PipelineOptions(streaming=True, save_main_session=True)
    user_options = pipeline_options.view_as(UserOptions)
{code}
Fails with:
{noformat}
Traceback (most recent call last):
  File "options.py", line 13, in <module>
    user_options = pipeline_options.view_as(UserOptions)
  File "/home/.../.virtualenvs/data-flow/lib/python3.6/site-packages/apache_beam/options/pipeline_options.py", line 335, in view_as
    view = cls(self._flags)
  File "/home/.../.virtualenvs/data-flow/lib/python3.6/site-packages/apache_beam/options/pipeline_options.py", line 205, in __init__
    cls._add_argparse_args(parser)  # type: ignore
  File "options.py", line 8, in _add_argparse_args
    _parser.add_value_provider_argument('--debug', action='store_true')
  File "/home/.../.virtualenvs/data-flow/lib/python3.6/site-packages/apache_beam/options/pipeline_options.py", line 125, in add_value_provider_argument
    self.add_argument(*args, **kwargs)
  File "/usr/lib/python3.6/argparse.py", line 1347, in add_argument
    action = action_class(**kwargs)
TypeError: __init__() got an unexpected keyword argument 'type'
{noformat}
Removing the `action` positional argument from the `add_value_provider_argument()` call gets rid of the error.
