[subsystem7]

Preview query for work part is giving a 500 error:

{"timestamp":1679322407326,"status":500,"error":"Internal Server Error","path":"/bdr:MW23703_2771::thumbnail/full/!300,300/0/default.dflt"}

well... lets take a shortcut for this one... instead of using bdr:MW23703_2771 let's:

• remove the initial M
• remove the _ and everything after it:

https://iiif.bdrc.io/bdr:W23703::thumbnail/full/!300,300/0/default.dflt

it's cheating a little bit... but since it will always work by construction let's use it for now
