Issue with Event Creation Using Circles - "Could not find organizer" Error

[dev-marcoC]

Steps to reproduce

• Create a Circle (team) in Nextcloud.
• Create a new calendar event and invite the Circle as participants.

Expected behavior

The event should be created successfully with the members of the Circle invited as participants, and the organizer field should be correctly assigned.

Actual behaviour

The event fails to create with the error message mentioned above, and the log shows the "Could not find organizer" exception. It seems that there is an issue with the synchronization of Circle members or the identification of the event organizer.

Additional info

When trying to create an event in Nextcloud and invite a team (Circle) I created, I encounter two issues:

The message:
"Note that members of circles get invited but are not synced yet."

The following error in the logs:
"ServiceException: Could not find organizer"

Additional Information:
I’ve verified that the Circle members are correctly configured and present in Nextcloud.
I’ve checked permissions and made sure my account has the necessary rights to create events.
I have tried creating events without using Circles, and it works fine, which suggests the issue is related specifically to the use of Circles.

The error message slightly differs, but the issue is identical.
