Problems with fieldname in event message

[powidian]

Hello,
I noticed that there was probably a problem with the field names contained in the event message payload.
The field names "EventType", "SourceNode", "ConditionId" have their field names automatically replaced by their "BrowseName" because they are of type "NodeId" ("ns=??;s=????").
Thus, once the event message is received, it is no longer possible to find the information "EventType", "SourceNode", "ConditionId" since their unique names are replaced by an unpredictable reference.
This regression occurred with commit 5823ae6 of August 2023. The addition of lines 240,241,242,243 are the cause. Deleting these lines makes this problem disappear.
I do not know the need that required the addition of these lines.
Can you update the code so that it no longer makes the identity of these fieldname disappear?
Thanks in advance
