OneCalender and NextCloud CalDav - <limit><nresults>1000</nresults></limit> unsupported

Hello,
I would like to use on my Windows10 clients OneCalendar Official Website to access the NextCloud calendar (Ver 1.7.1 running on NextCloud 17.0.1) since the Microsoft calendar app does only synch the next 5 months properly. Unfortunately according to the OneCalendar hotline the NextCloud CalDav implementation does not support the limit tag and thus throws an exception:

Your CalDAV server doesn’t fully support the CalDAV protocol. We’re asking for all appointments with a limit, so we don’t get to process hundreds of thousands of appointments at once. But your server doesn’t support that.

Part of the error message:
<d:error xmlns:d="DAV:" xmlns:s="http://sabredav.org/ns">
<s:exception>OCA\DAV\Exception\UnsupportedLimitOnInitialSyncException</s:exception>
<s:message/>
<d:number-of-matches-within-limits/>
</d:error>

RequestData: <sync-collection xmlns="DAV:">
<sync-token />
<sync-level>1</sync-level>
<limit>
<nresults>1000</nresults>
</limit>
<prop>
<getetag />
</prop>
</sync-collection>
ResponseData: <?xml version="1.0" encoding="utf-8"?>
<d:error xmlns:d="DAV:" xmlns:s="http://sabredav.org/ns">
<s:exception>OCA\DAV\Exception\UnsupportedLimitOnInitialSyncException</s:exception>
<s:message/>

</d:error>

Does anybody know how to configure nextcloud to solve this issue or is this a new feature request?

That sounds like that this isn’t a configuration but a missing feature issue. You should open an issue ticket in the Calendar repository to raise the awareness for this problem.
