      As reported in https://github.com/mongodb-labs/mongo-arrow/issues/164, pymongoarrow produces incorrect projections on nested fields which cab lead to unexpected errors.

      >>> import pymongoarrow.api
      >>> import pyarrow as pa
      >>> schema = pymongoarrow.api.Schema({'_id': pa.int32(), 'obj': {'a': pa.int32()}})
      >>> schema._get_projection()
      {'_id': True, 'obj': True}
      

      The expected behavior should be:

      >>> schema._get_projection()
      {'_id': True, 'obj': {'a': True}}
