We would need some more info about how you got to this exception. What are you trying to do? Which process are you trying to render?

[shekhar_shaw]

I am getting the same exception. Please suggest.

I am attaching my process code here.

@shekhar.shaw

Your process contains an empty process which is causing the issue, removing it the diagram is generated successfully.


<process id="process_pool1" name="process_pool1" isExecutable="true">
    <laneSet id="laneSet_process_pool1">
      <lane id="lane1"></lane>
    </laneSet>
  </process>
