Hi there,
trying to run stream listener to consume messages in sync. got this error.
async message listener is working. trying to get messages in bulk to process them at once.

/code-envs/python/py39_dn001/lib/python3.9/site-packages/factiva/news/stream/listener.py in _pull_pubsub_messages(self, pubsub_client, pubsub_request, subscription_path, callback, ack_enabled)
    225 
    226         """
--> 227         pubsub_messages = pubsub_client.pull(request=pubsub_request)
    228         if pubsub_messages and pubsub_messages.received_messages:
    229             for message in pubsub_messages.received_messages:

/code-envs/python/py39_dn001/lib/python3.9/site-packages/google/cloud/pubsub_v1/_gapic.py in <lambda>(self, *a, **kw)
     38             return staticmethod(functools.wraps(wrapped_fx)(fx))
     39         else:
---> 40             fx = lambda self, *a, **kw: wrapped_fx(self.api, *a, **kw)  # noqa
     41             return functools.wraps(wrapped_fx)(fx)
