Hi,

I’ve upgraded Camunda Modeler to 1.12.0, and it looks like the new version cannot handle some of my diagrams. When I try to move elements around, I get the following error:

TypeError: Cannot convert undefined or null to object

The previous version, 1.11.3, works fine with all my diagrams.

Here is an example of a diagram that fails in 1.12.0 but works in 1.11.3.
