get_parent() returns wrong parent

[Statkern15]

Hello,
i just found a strange behaviour when i tested a method call on a new OPC-Server i got a work.
My script normally gets the method_id and then calles the get_parent() method on that node to get the correct parent.

method_node = client.get_node(node_id) 
parent_node = await method_node.get_parent()

This worked fine for multiple different machines until now. However with this machine the get_paren method returns the InputArgument variable instead of the object node.


I am not quite sure if this is Bug in the libary or on the machine itself. When i call the method directly from UaExpert it works as expected.

I’m not sure whether this is a bug in the library or a server-specific behavior. Calling the method directly from UaExpert works as expected.
I would appreciate any input on whether I’m missing something in my approach.
Thanks in advance.

Nevermind i missed the comment that the get_parent() method uses reverse references. And when i checked by server does not have those references.
