some files can't be downloaded

[kosarko]

Not sure what the pattern is, but the browser shows just a whitelabel 500 error or if using curl

{"timestamp":"2023-10-27T15:38:02.929+00:00","status":500,"error":"Internal Server Error","message":"An exception has occurred","path":"/repository/api/core/bitstreams/handle/11234/1-3185/PDT-C-1.0.zip"}

the backend log shows:
