Persistant error with Nextcloud Client Android and Nextcloud Desktop

On Android I´ve setup Nextcloud to automatic upload

  • /storage/disk/DCIM/OpenCamera to
  • /InstantUpload/OpenCamera
  • With only Upload over WLAN checked the rest uncheck

OpenCamera saves new images (JPG and DNG) to /storage/disk/DCIM/OpenCamera

When I take a picture with OpenCamera it is stored and uploaded to NextCloud server and appears in /InstantUpload/OpenCamera folder.

When the Nextcloud Client on Fedora starts a sync it consistanly runs in an error:

File with name /InstantUpload/OpenCamera/name could not be found.

If I uncheck /InstantUpload on the desktop client it does indeed not sync but gives no errors.

How do I setup my phone, nextcloud server and nextcloud client to sync the files without error?
