### Search before asking - [X] I had searched in the [issues](https://github.com/apache/dolphinscheduler/issues?q=is%3Aissue) and found no similar feature requirement. ### Description In version 3.1.0, the global variable of process cannot be null. Is there any design consideration? For some processes, the value of the global variable is not fixed, so we do not set the default value of the global variable when defining the process, and the determined value of the global variable will be passed in when calling the run api. Compared with 2. x and 1. x versions, global variables can be set to null.  ### Are you willing to submit a 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.
