Just noticed this sample isn't on https://cloud.google.com/pubsub/docs/create-cloudstorage-subscription

[lahuang4]

Oh interesting, I found it from https://cloud.google.com/pubsub/docs/samples/pubsub-create-cloud-storage-subscription#pubsub_create_cloud_storage_subscription-python.

Will look into updating the https://cloud.google.com/pubsub/docs/create-cloudstorage-subscription page to link all the existing samples.

It looks like the Kokoro build failed, but it was a different test case which failed:

=================================== FAILURES ===================================
__________________ test_opentelemetry_flow_control_exception ___________________

...

        spans = span_exporter.get_finished_spans()
        # Span 1 = Publisher Flow Control Span of first publish
        # Span 2 = Publisher Batching Span of first publish
        # Span 3 = Publisher Flow Control Span of second publish(raises FlowControlLimitError)
        # Span 4 = Publish Create Span of second publish(raises FlowControlLimitError)
>       assert len(spans) == 4
E       assert 5 == 4
E        +  where 5 = len((, , ))

tests/unit/pubsub_v1/publisher/test_publisher_client.py:301: AssertionError

@hongalex could you help me re-run the Kokoro check? Not sure how to trigger it myself.

(Looks like there is already an issue opened for the test being flaky: #1309)
