I must have started to create it a while ago and never deployed it. Now I can't complete the Enable Lightning Components project in trailhead because there is no place to check 

  I am getting the following error message: There was an unexpected error in your org which is preventing this assessment check from completing: System.DmlException: Update failed. First exception on row 0 with id 0063600000QNxSzAAL; first error: CANNOT_EXECUTE_FLOW_TRIGGER, The record couldn’t be saved because it failed to trigger a flow.
