In the workflow definition w2, use the dependent task node to select the workflow definition w1, and the time is today. Trigger w1 regularly to generate a w1-1 workflow instance to keep the task running; manually generate a w1-2 workflow instance to keep the task running. A workflow instance of w2 is generated regularly, and a null pointer exception will be reported if the dependent task node. ### Anything else _No response_ ### Version 3.1.x ### Are you willing to submit PR? - [X] 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.
