I am using the following script to rename the node to the discovered snmp name 

9  if (($node.snmpSysName != "") and ($node.snmpSysName !=null))
10 {
11 return $object.rename($node->snmpSysName);
12 }

I always get this error and Im not sure why as it compiles and runs without issue
Script (Hook::ConfigurationPoll) execution error: Error 14 in line 9: Function or operation argument is not an object

This hook is not limited to Nodes, so $node can be null while $object is set.
If you are interested in nodes only, just check for $node:

if ($node and not $node.snmpSysName.isEmpty()) {
   $node.rename($node.snmpSysName);
}


Thank you.. Is this still needed ?  I see that the server config has the following 

Objects.Nodes.ResolveNames   according to the description this resolves using DNS,SNMP system name ...

Objects.Nodes.ResolveNames - this works only when node is created. 
There's Objects.Nodes.SyncNamesWithDNS, but this one is taking names from DNS only (also not that activating this parameter currently requires server restart which contradicts with what UI is saying - it's a bug)
