Start with tests/sentry/uptime/endpoints/test_organization_uptime_alert_index.py, especially test_owner_filter and its check_valid_response helper. Run the named test and compare the expected and actual response ordering shown in the failure; done means the test passes reliably without the reported mismatch.
