Start with the assertion in caldav/lib/error.py at the line shown in the traceback, then trace its callers to identify which condition fails during Infomaniak calendar and task synchronization. The report does not expose that condition or name a test; done means identifying the failure and confirming normal synchronization no longer logs the assertion.
