Datastore.Client.Query.fetch().next_page() always return has_next = False

[getumen]

Using

gcloud==0.18.1

fetch().has_next() doesn't work.
It always returns False.

from gcloud import datastore

if __name__ == '__main__':
 ds = datastore.Client('project-id')

 has_next = True
 cursor = None

 for i in range(10):
 query = ds.query(kind='Item')
 query.keys_only()
 entity, has_next, cursor = query.fetch(start_cursor=cursor, limit=1).next_page()
 print(entity, has_next)

The result is following:

[<Entity[{'kind': 'Item', 'id': 1}] {}>] False
[<Entity[{'kind': 'Item', 'id': 2}] {}>] False
[<Entity[{'kind': 'Item', 'id': 3}] {}>] False
[<Entity[{'kind': 'Item', 'id': 4}] {}>] False
[<Entity[{'kind': 'Item', 'id': 5}] {}>] False
[<Entity[{'kind': 'Item', 'id': 6}] {}>] False
[<Entity[{'kind': 'Item', 'id': 7}] {}>] False
[<Entity[{'kind': 'Item', 'id': 8}] {}>] False
[<Entity[{'kind': 'Item', 'id': 9}] {}>] False
[<Entity[{'kind': 'Item', 'id': 10}] {}>] False

There are next entities. But has_next() returns False.
This issue occurs since about 4 hours ago.

Based on the timing, I wonder if this issue is a symptom of the same problem as #2204.

The underlying issue of #2204 was indeed a problem across a whole bunch of services. Python was affected, but not other languages.

Sorry, I misunderstand the datastore specification.
