I will eventually fix the NPE but the issue is that once again, you used the readonly reference to the object rather than the locked view.

In my case, I need to create elements (nodes and node) based on information that is in the node-agents and node-agent elements in v2. I then need to remove the node-agents references from the config. I tried to create a nodes elements but get the stace trace below.
