Calendar error "/trashbin/Objects not implemented" when syncing calendar data [SOLVED]

I am running nextcloud in a VM with no outside access to the internet. This is a new install with latest release. I am using Emclient to access the calendar. The main focus of nextcloud is calendar use. When syncing emclient to nextcloud I get the following error in emclient:

  8:39:36 AM user [CalDAV / CardDAV]  Synchronizing subfolders: For folder user/trashbin/objects/
    8:39:37 AM user [CalDAV / CardDAV]  MailClient.Storage.Application.OperationException: Subfolder synchronization for folder "objects" failed due to the following error: Not Implemented.

Once again, Nothing in the logs about this and appears to be a calendar/trashbin issue. However, I have searched for similar problems for this and havent found any. Otherwise emclient works fine and calendars do display. Everything about Nextcloud seems to work fine otherwise.

I am new to nextcloud, Thank you.

I got this… Solved.
Emclient version 7 produces this error with some compatibility issue. I upgraded to emclient version 8.whatever and the error no longer is there. I will mark this solved.
