Updating existing / Uploading new record - EXCEPTION at.bitfire.dav4android.exception.NotFoundException: 404

raoulbhatia

Hi!

Since I’ve updated to the owncloud calendar 1.4.1 and owncloud 9.1.2 that is actually developed under the nextcloud umbrella [1], I am facing an issue when I am creating/updating entries via the Android calendar:

The only way I found to resolve this is to delete the added/modified entry and re-add this via Owncloud.
This used to work until the update to calendar 1.4.1 and owncloud 9.1.2.

Happy to provide more information to get this resolved.

Thanks,
Raoul

Hello,

This seems to be a server problem. DAVdroid uploads the iCal, and the server returns 404 Not Found – is there any indication that this could be a DAVdroid problem?

I guess it’s related to uploading events to a shared calendar.

Thanks

raoulbhatia

@rfc2822 thanks for your quick reply. I wasn’t sure and have created an issue for

owncloud at https://github.com/owncloud/core/issues/26667
nextcloud at https://github.com/nextcloud/server/issues/2402

@raoulbhatia Thanks. If there are any indications that this could be a DAVdroid problem, please post them here.
