Storage exists but reported as not existing and existing (?)

During registration it is possible that same storage with slightly different parameters cannot be recognized. In my case the storage was initially created by timeseries (zarr) registration, then I tried to register regular products and ran into the following. Storage.get_or_create attempts to retrieve probably, fails, and tries to create with same name already existing.

A workaround currently is to rename existing storage.
