Why is StatusCode 'Good' when writing to non-existing node?

[jmass172023]

I have a python script that loads multiple node ids from a config file and writes values to them. I was checking the returned status code to see if the write operation was successful but it doesn't seem to catch if a tag name is invalid. One of the tag names was misspelled but the returned status code after the write says it was 'Good'. Why is that?
#sample write of multiple values
nodes =[]
values=[]
nodes.append(client.get_node('ns=2;s=Test1'))
nodes.append(client.get_node('ns=2;s=Test2'))
nodes.append(client.get_node('ns=2;s=Test3'))
nodes.append(client.get_node('ns=2;s=X')) # This node name is invalid but get Good status on write
values.append(ua.DataValue(ua.Variant('One11', ua.VariantType.String)))
values.append(ua.DataValue(ua.Variant('Two22', ua.VariantType.String)))
values.append(ua.DataValue(ua.Variant('Three33', ua.VariantType.String)))
values.append(ua.DataValue(ua.Variant('Four44', ua.VariantType.String)))

    await client.set_values(nodes,values)

The return code is send by the server and we check for every result. So either the node exists or the server does send a StatusCode Good. Best way to check this is to make a wireshark trace. There you can see the Statuscodes send by the server.

Thanks. I found the problem was a setting on the UA server that creates nodes when a client tries to access them even if they don't exist. The tag was being created dynamically and being written to successfully.
