Start by running tests/sentry/incidents/serializers/test_workflow_engine_detector.py::TestDetectorSerializer::test_simple and compare serialized_detector with self.expected. Investigate the differing trigger entries and their ordering or values shown in the failure, then rerun the test repeatedly; done means the test passes consistently.
