KeyError after upgrade to 4.1.2

Did recently upgrade two instances of EDMS to v4.1.2, from the version 3.4.11. Since this change I observe exceptions for around two thirds of the requests going into the cabinet tree due to a KeyError.

The traceback which I see is as follows:

mayan.apps.logging.middleware.error_logging <41> [ERROR] "process_exception() line 17 Exception caught by request middleware; <WSGIRequest: GET '/cabinets/cabinets/61/?page=2'>, 'resolved_object'"
Traceback (most recent call last):

    raise KeyError(key)
KeyError: 'resolved_object'

In order to reproduce the issue, I just have to open the Cabinets overview or a specific page within a Cabinet. Example paths:

  • GET '/cabinets/cabinets/61/?page=2'
  • GET '/cabinets/cabinets/'

I've not yet managed to set up a test instance and reproduce the issue there from scratch. If I manage to do so I'll comment here on the issue with the details.
