> 1.According to the above steps, there is still no reproduction > 2. Please check the preTasks field value of the database table t_ds_process_definition.process_definition_json，If the preTasks are empty, it should be caused by not clearing the cache when creating the workflow definition. You can clear the browser cache and re-edit the workflow definition well, Because the problem was fixed by me, when the problem reappears, I will verify the solution you provided, and I temporarily closed the problem. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
