OPC-UA Method Call

Industrial

Hi,
I'm trying to call an OPC-UA method. Input parameters are handled in a function node.

msg.objectId = "ns=2;s=Sinumerik";
msg.methodId = "ns=2;s=/Methods/Filehandling/Select";
//msg.fname=flow.get("fname");
msg.inputArguments = [
    { dataType: "String", value: "Sinumerik/FileSystem/Work Pieces/TECHNIKER/MESS.MPF"},
    { dataType: "UInt32", value: 1}
];
return msg;

Error:Execute method result, error:The node id refers to a node that does not exist in the server address space.
Copied the identifier from UAExpert:

I'm not sure if the identifier of the method or of the input argument is the problem.
If I call the method in UAExpert directly it works.
Any thoughts about this?
Thx,
Steve

You need to provide method parent nodeId as objectId that contains method.
And methodId nodeId to call method.
