I found that this error occurs after stopping the task and deleting the
process instance，The corresponding task instance is also deleted.
The error occurred in：
org.apache.dolphinscheduler.server.master.runner.WorkflowExecuteThread
private boolean taskStateChangeHandler(StateEvent stateEvent) {
TaskInstance task =
processService.findTaskInstanceById(stateEvent.getTaskInstanceId());
**if (task.getState().typeIsFinished())** {
taskFinished(task);
} else if
(activeTaskProcessorMaps.containsKey(stateEvent.getTaskInstanceId())) {
ITaskProcessor iTaskProcessor =
activeTaskProcessorMaps.get(stateEvent.getTaskInstanceId());
iTaskProcessor.action(TaskAction.RUN);
if (iTaskProcessor.taskState().typeIsFinished()) {
task =
processService.findTaskInstanceById(stateEvent.getTaskInstanceId());
taskFinished(task);
}
} else {
logger.error("state handler error: {}", stateEvent.toString());
}
return true;
}
