how so? It must be both, file based and allow the import content type?

Besides above, the error would now be wrong too, it states:

"storage selected for extraction does not support 'images' content type or is not file based"

(not (support 'images' content type)) or is (not (file based))

Exactly what Dominik used.

The fix here would add the 'images' content-type as supported one for
CephFS.
