redmine_dmsf plugin version 3.1.3: 500 Internal Server Error

[deining]

I'm running latest redmine_dmsfplugin (version 3.1.3). My colleague encountered am error while trying to access the DMS. From the logs:

I myself with an admin account can access the resource without problems. Any idea what's going wrong here?

That's my setup:

Environment:
  Redmine version                5.1.0.stable
  Rails version                  6.1.7.6
  Environment                    production
  Database adapter               PostgreSQL
  Mailer queue                   ActiveJob::QueueAdapters::AsyncAdapter
  Mailer delivery                smtp
Redmine settings:
  Redmine theme                  Default
SCM:
  Git                            2.43.0
  Filesystem                     
Redmine plugins:
  redmine_dmsf                   3.1.3
  redmineup_tags                 2.0.13

Thanks for your assistance. And thanks for providing redmine_dsmf plugin!
