Again if I select option 13

You have not set a DataType(Id) for your node so it is the abstract BaseDataType. The sample would try to convert your input based on the DataType, but given it is the base, we do not have any java Class mapping for that, thus the conversion cannot be done.
Also for any other attribute than value the WriteMask/UserWriteMask should have the equivalent bit set in order to allow writing. However typically no server will allow writing to them. And for value the AccessLevel/UserAccessLevel must have CurrentWrite bit set in order to allow writing values).

I meant setting the DataTypeId in the server side/code/application.

After starting server/ running SampleConsoleServer application I got the following menu and there is no provision for setting the dataTypeId after adding node.
——————————————————-
– Enter D to enable/disable server diagnostics
– Enter a to add a new node
– Enter d to delete a node
– Enter e to send an event
– Enter r to Add a Reverse Connection to a Client
– Enter x to close the server

I guess you are the first person to actually try to write to those nodes. I guess it could be improved at some point.
However note that both applications are samples for how to use the SDK, not full applications (even through they have a lots of basic functionalities), i.e. you will need to do this in the sampleconsoleserver example’s code yourself. Look at e.g. com.prosysopc.ua.samples.server.compliancenodes.ComplianceNodeManager. Or first try to write to e.g. Objects/ComplianceNodes/StaticVariables/Int32 on the sampleconsoleserver, that should work.
