Bug #10578: Cannot add node property when audit message is mandatory
Cannot change policy mode when audit message is mandatory (4.0)
Major - prevents use of part of Rudder | no simple workaround
Operational - other Techniques | Technique editor | Rudder settings
In the parent ticket, we corrected the same problem for both policy mode and node properties in 4.1.
The policy mode part must be backported to 4.0.
