Client crash when writing a data type different from the one set in the OpcUa-Item #632

We noticed that the client crashes when writing a data type different from the one set in the OpcUa-Item. In particular, setting "String" and injecting a timestamp results in this Uncaught Exception:


Session created for node: WRITE TEST
Writing datatype: 12 value: 1700745221747
23 Nov 13:13:41 - [red] Uncaught Exception:

Fix your flow first, I will look this later. No time at the moment.

Yes we fixed it, we just wanted to point this out :)
