### Search before asking - [x] I had searched in the [issues](https://github.com/apache/dolphinscheduler/issues?q=is%3Aissue) and found no similar issues. ### What happened workflow instance keep stuck in Ready_Stop Status. <img width="3218" height="382" alt="Image" src="https://github.com/user-attachments/assets/4daf86dd-20b0-40ed-8b19-3ccafa81f319"; /> ### What you expected to happen workflow instance with STOP status in the end. ### How to reproduce how to reproduce it: 1. create some parallel execution task nodes, all of which have downstream nodes. The faster these task nodes end, the higher the probability of replication. 2. in my env, all the shell node only execute echo 1. 3. start workflow instance, and stop it immediately. <img width="3184" height="1248" alt="Image" src="https://github.com/user-attachments/assets/6ba3d276-8a2d-48c2-9d82-5e7cd3e3aef8"; /> ### Anything else 1. when process instance in Ready_Stop state, dolphinscheduler will send workflow state change event to this process instance, this event call KillAllTasks 2. at this moment, TaskStateEventHandler received task finished event, will call workflowExecuteRunnable.taskFinished, and submitPostNode 3. submitPostNode will submit standby tasks, if a standby task dependResult is success, ds need save it to db, and there's bug here <img width="2342" height="944" alt="Image" src="https://github.com/user-attachments/assets/e0d99e71-7fcb-4b27-8f49-0960253c59aa"; /> 4. submitTaskExec failed means task id is null, Map put (null, xx) will throw npe exception. <img width="3770" height="854" alt="Image" src="https://github.com/user-attachments/assets/c64bb440-be72-4fd3-9365-67883e97623b"; /> 5. this exception without any handle method, so workflowExecuteRunnable.stateEvents never remove the finished event, means workflowExecuteRunnable need keep dealing with this event all the time, it's endless loop ### Version 3.1.x ### Are you willing to submit PR? - [ ] Yes I am willing to submit a PR! ### Code of Conduct - [x] I agree to follow this project's [Code of Conduct](https://www.apache.org/foundation/policies/conduct) -- This is an automated message from the Apache Git Service.
