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:

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

Any help would be helpful.
