Modeler export app crashes with duplicated processes

Hi, I created on Modeler with 1 CMMN and 3 BPMN(one of them is subprocess). I added all 4 artifacts to app and tried exporter to zip. I got exception in logs, but not in UI that I am adding duplicates. My proposal just skip artifacts that are duplicated. I submitted pull request 3187.

Could someone share if my fix is acceptable or I am misusing something.

Thanks for the PR! We regularly review PR’s and respond there, no worries :-).

Thank you. I will be patient then :slight_smile:
