Hi,

I use "google_api_python_client-1.5.1" from pip.
I try Pub/Sub message publish to topic.

topics.publish(topic='topicId',
               body={
                     'messages': [{
                                   'messageId': str(uuid.uuid4()),
                                   'data': base64.encodestring('Hello')
                                  }]
                     }).execute()

error occurred, and return this message.

googleapiclient.errors.HttpError: <HttpError 400 when requesting https://pubsub.googleapis.com/v1/projects/projectId/topics/topicId:publish?alt=json returned "Invalid value at 'messages[0].data' (TYPE_BYTES), "SGVsbG8=
