I guess I fixed this in UCS 4.2, not sure though.

Version: 4.1-4 errata0

Errata 0 seems unlikely with UCS 4.1-4

Tested with:

Login to UMC
# pkill -f console-module
# service slapd stop
Open a UDM module
----

Before patch: shows traceback
After patch: shows human readable error message

YAML: OK

-> Verified
