The error message "AttributeError: 'dict' object has no attribute 'result'" is returned when calling result() to get the response from a future object created by the ArcGIS API for Python’s cleanup_change_tracking.
This issue is not reproducible in ArcGIS API for Python version 2.4.2, which is scheduled for release in Q4 2025. Update to this version if the issue persists.
Additionally, verify that the hosted feature services are set up correctly. If the issue persists, contact Esri Support Services.
