Issue Summary

      Moving issues with assigned epic across kanban backlog and divided kanban backlog area is throwing a javascript error. Problem occurs on kanplan, I couldn't reproduce it on scrum backlog. After first occurrence an error will be thrown for each drag & drop. The core functionality of dragging issues works but the usability of it is pretty low and may have side effects.

      Environment

      • macOS Mojave 10.14
      • Google Chrome 72

      Steps to Reproduce

      1. Create a kanban project
      2. Enable kanplan
      3. Get a backlog of variety issues (with and without epic).
      4. Try to move an issue with assigned epic to divided kanban backlog area
      5. After D&D javascript error will throw

      Expected Results

      Moving issues across kanban backlog works without errors. 

      Actual Results

      The below exception is thrown:

      Exception: Uncaught TypeError: Cannot read property 'text' of undefined
      

      Notes

      It works properly on 7.13.x

      Workaround

      Currently there is no known workaround for this behavior. A workaround will be added here when available
