when running bin/dspace filter-media
     it throws NullPointerException

it worked until today.

possible cause:
yesterday the cron ran 
bin/dspace cleanup

also new items have come in.

The error logs say:

2024-03-08 11:09:34,089 INFO  unknown unknown

It would have been useful if the logs told me the bitstream that caused 
this error.

Any help would be helpful.
