I am trying to publish messages to Google PubSub in Python
Here is the code that I tried
from google.cloud import pubsub
ps = pubsub.Client()
topic = ps.topic("topic_name")
topic.publish("Message to topic")
I am getting the below error
File "/usr/local/lib/python2.7/dist-packages/google/cloud/iterator.py", line 218, in _items_iter
for page in self._page_iter(increment=False):
File "/usr/local/lib/python2.7/dist-packages/google/cloud/iterator.py", line 247, in _page_iter
page = self._next_page()
File "/usr/local/lib/python2.7/dist-packages/google/cloud/iterator.py", line 445, in _next_page
items = six.next(self._gax_page_iter)

return self.__next__()

' classified as transient', exception)
google.gax.errors.RetryError: GaxError(Exception occurred in retry method that was not classified as transient, caused by <_Rendezvous of RPC that terminated with (StatusCode.PERMISSION_DENIED, User not authorized to perform this action.)>)
I've download service-account.json and the path of service-account.json is set to GOOGLE_APPLICATION_CREDENTIALS
I've also tried installing gcloud and executing gcloud auth application-default login
Please note that I am able to publish message using gcloud command and in java
$ gcloud beta pubsub topics publish sample "hello"
messageIds: '127284267552464'
Java code TopicName topicName = TopicName.create(SRC_PROJECT, SRC_TOPIC);
Publisher publisher = Publisher.defaultBuilder(topicName).build();
ByteString data1 = ByteString.copyFromUtf8("hello");
PubsubMessage pubsubMessage1 = PubsubMessage.newBuilder().setData(data1).build();
publisher.publish(pubsubMessage1);
What is missing in python code?
I followed the steps described over here
