Hi,
I've got it in my logs:
File "/base/data/home/apps/contact-birthdays/1.336002949603692439/
birthdaysapp/views.py", line 123, in index_view
read_only = not(capabilities.CapabilitySet('datastore_v3',
['write']).is_enabled())
File "/base/python_lib/versions/1/google/appengine/api/capabilities/
__init__.py", line 98, in is_enabled
config = self._get_status()
File "/base/python_lib/versions/1/google/appengine/api/capabilities/
__init__.py", line 167, in _get_status
self._stub_map.MakeSyncCall('capability_service', 'IsEnabled',
req, resp)
File "/base/python_lib/versions/1/google/appengine/api/
apiproxy_stub_map.py", line 72, in MakeSyncCall
apiproxy.MakeSyncCall(service, call, request, response)
File "/base/python_lib/versions/1/google/appengine/api/
apiproxy_stub_map.py", line 255, in MakeSyncCall
rpc.CheckSuccess()
File "/base/python_lib/versions/1/google/appengine/api/
apiproxy_rpc.py", line 111, in CheckSuccess
raise self.exception
OverQuotaError: The API call capability_service.IsEnabled() required
more quota than is available.
There's nothing in the dashboard, but quotas have been reset since
I've started receiving this exception, now everything's ok.
Application id: contact-birthdays
Regards,
Pedro Morais
