Noticed following exception in logs. This seems to happen when the build has just started, and ews-app has received the build-start event, but not the first step-start event. We should handle it appropriately. 2019-04-06 11:22:44,444 - Internal Server Error: /status-bubble/366884/ Traceback (most recent call last): File "/usr/lib/python2.7/site-packages/django/core/handlers/exception.py", line 41, in inner response = get_response(request) File "/usr/lib/python2.7/site-packages/django/core/handlers/base.py", line 187, in _get_response response = self.process_exception_by_middleware(e, request) File "/usr/lib/python2.7/site-packages/django/core/handlers/base.py", line 185, in _get_response response = wrapped_callback(request, *callback_args, **callback_kwargs) File "/usr/lib/python2.7/site-packages/django/views/generic/base.py", line 68, in view return self.dispatch(request, *args, **kwargs) File "/usr/lib/python2.7/site-packages/django/views/generic/base.py", line 88, in dispatch return handler(request, *args, **kwargs) File "/usr/lib/python2.7/site-packages/django/views/decorators/clickjacking.py", line 58, in wrapped_view resp = view_func(*args, **kwargs) File "/var/ews/OpenSource/Tools/BuildSlaveSupport/ews-app/ews/views/statusbubble.py", line 193, in get bubbles, show_submit_to_ews, show_failure_to_apply = self._build_bubbles_for_patch(patch) File "/var/ews/OpenSource/Tools/BuildSlaveSupport/ews-app/ews/views/statusbubble.py", line 182, in _build_bubbles_for_patch bubble = self._build_bubble(patch, queue) File "/var/ews/OpenSource/Tools/BuildSlaveSupport/ews-app/ews/views/statusbubble.py", line 111, in _build_bubble timestamp = self.get_build_timestamp(build) File "/var/ews/OpenSource/Tools/BuildSlaveSupport/ews-app/ews/views/statusbubble.py", line 130, in get_build_timestamp return self._iso_time(build.step_set.last().started_at) AttributeError: 'NoneType' object has no attribute 'started_at'
