How to reproduce

[ERROR] 2021-11-11 14:31:19.462 org.apache.dolphinscheduler.server.worker.runner.TaskExecuteThread:[210] - task scheduler failure

private void sendAttachment(int groupId, String title, String content) {
setNeedAlert(Boolean.TRUE);
TaskAlertInfo taskAlertInfo = new TaskAlertInfo();
taskAlertInfo.setAlertGroupId(groupId);
taskAlertInfo.setContent(content);
taskAlertInfo.setTitle(title);
}

Forget to setTaskAlertInfo?

private void sendAttachment(int groupId, String title, String content) {
setNeedAlert(Boolean.TRUE);
TaskAlertInfo taskAlertInfo = new TaskAlertInfo();
taskAlertInfo.setAlertGroupId(groupId);
taskAlertInfo.setContent(content);
taskAlertInfo.setTitle(title);
setTaskAlertInfo(taskAlertInfo);
}
