   rebuilt, it may be helpful in finding the best way forward or, at
   least, understanding the repository's current state.
I do think we figured out how the mess came to be.  I think they 
restored a database from a defunct dspace install, not realizing that 
there was no backup of the assetstore.  So, basically, the file is 
missing but all the database side of stuff is there. Since we know the 
date we rebuilt, we should be able to find all the items which have been 
created before that time and "fix" those.  It looks like we can 
initially do a search of something like: dc.date.issued:[1999 TO 
2024-03-20] to find all the records.
They still do have most of the assets in digital form, but it will be 
work to find them scattered across multiple computers.  It looks like 
the best process for fixing them, if we have the original file, is 
follow these instructions you gave:
   It is possible to delete an existing bitstream from, and to up load
   a new one to, an Item when logged in with appropriate rights (such
   as a member of the Administrator group). Navigate to the Item, use
   the pencil / Edit this item button at top right, select the
   Bitstreams tab, and you'll see a list of bitstreams with action
   buttons, plus uploading controls at the top.

And then we will have the joyous task of dealing with all the ones that fall through the cracks, whether because they cannot find the original file, or because the item was somehow skipped when they were fixing.
Anyway.  I think you have helped; at least I know where things stand.  
It may be easier for them to bulk delete all the ones that are certainly 
no longer there and simply upload all the ones that they do have.  I 
will let them figure that one out.

This application has no explicit mapping for /error, so you are seeing this as 
a fallback.
