Issue in writing a OPC-Tag/Variable - Invalid variant Boolean value:1 about opcua-commander

[georges-schutz]

By the way I also tested scalar string type variables and they also work fine.
I do not have a setup with arrays so I could not test that so far.

Hi again
I have now also tested an array variable and I get an exception while attempting to write.

Error: Matrix Variant : missing dimensions
    at constructHook (/opt/opcuacommander/node_modules/node-opcua-variant/source/variant.ts:449:23)
    at new Variant (/opt/opcuacommander/node_modules/node-opcua-variant/source/variant.ts:112:26)
    at Model.writeNode (/opt/opcuacommander/lib/model/model.ts:311:21)
    at processTicksAndRejections (node:internal/process/task_queues:94:5)
    at Form.<anonymous> (/opt/opcuacommander/lib/view/view.ts:238:23)

It does show me the list of items in the array fine in the write-popup but when submitting the exception occurs

Please contact [email protected] , there must be inconsistencies in your OPCUA Server variables,

Hello,
my OPCUA server that I use for local testing is a python based FreeOPCUA server [1].
I use the corresponding GUI [2] but also the more generic UAExpert [3] for testing compatibilities.
I have also access to several other operational OPCUA servers from some clients [divers products] but there I am not flexible to add variables and I also do not want to risk any thing on this systems.

I will check to update to the latest version of the FreeOPCUA server in order to ensure latest compatibilities and potential opcua protocol fixes but I doubt that the Boolean issue comes from there. It is possible that the array test where "Error: Matrix Variant : missing dimensions" could come from this kind of incompatibilities.

I will keep you informed
Georges
