That’s something that gets added automatically when adding a connection and while moving the mouse it fires the “connection.create” above and adds it to my map,also I’m loading this xml file at the start:
<bpmn:definitions xmlns:bpmn="http://www.omg.org/spec/BPMN/20100524/MODEL"

</bpmn:definitions>
I wasn’t sure bpmn:process was necessary or not so I just left it, but since in the map variable it didn’t cause any problems I can just ignore it.
