Hi, Since last version we got some exceptions (All same) linked apparently to privat event in calendar

System.NullReferenceException: Object reference not set to an instance of an object. at DDay.iCal.Event.get_IsAllDay() at CalDavSynchronizer.Implementation.Events.EventEntityMapper.Map2To1(IEvent source, IReadOnlyCollection1 recurrenceExceptionsOrNull, IAppointmentItemWrapper targetWrapper, Boolean isRecurrenceException, IEntitySynchronizationLogger logger, IEventSynchronizationContext context) at CalDavSynchronizer.Implementation.Events.EventEntityMapper.Map2To1(IICalendar sourceCalendar, IAppointmentItemWrapper target, IEntitySynchronizationLogger logger, IEventSynchronizationContext context) at GenSync.Synchronization.States.UpdateBToA7.d6.MoveNext() --- End of stack trace from previous location where exception was thrown --- at System.Runtime.ExceptionServices.ExceptionDispatchInfo.Throw() at System.Runtime.CompilerServices.TaskAwaiter.HandleNonSuccessAndDebuggerNotification(Task task) at GenSync.Synchronization.States.UpdateBToA`7.JobWrapper.d13.MoveNext() --- End of stack trace from previous location where exception was thrown --- at System.Runtime.ExceptionServices.ExceptionDispatchInfo.Throw() at System.Runtime.CompilerServices.TaskAwaiter.HandleNonSuccessAndDebuggerNotification(Task task) at CalDavSynchronizer.Implementation.Events.OutlookEventRepository.d23.MoveNext() --- End of stack trace from previous location where exception was thrown --- at System.Runtime.ExceptionServices.ExceptionDispatchInfo.Throw() at GenSync.EntityRepositories.BatchEntityRepositoryAdapter`4.d3.MoveNext()

We sync with Infomaniak system in Switzerland. Maybe the error come from them.

The exception seems to be "NullReferenceException".

Thank you for your help.

Can you post the ics file of the event in the sync report that causes this error?

I don't know if this is this file you need :

34adb592-268f-48c8-9924-800d4af57ddf20230502172342010.log

This file was in AppData/Local/CalDavSynchronizer/xxx

In this sync report there should be a link to server id and there you can download the raw data of that event, /calendars/JC05088/bff3257e-239f-47cb-bbc1-1cb1ca40bccd/8b6cf2dd-f159-477c-994e-811ddfeeff53.ics

Here you can find the file :

I change the extension to .txt but this is my .ics. (Github don't accept this extension)
