### 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         When doing the multi-table accuracy verification of data quality, after maintaining the ON statement and other necessary configuration parameters on the front-end interface, the task execution fails, and it is found that the key value of mapping_columns is missing in the data quality task params, which causes the back-end to report a Json deserialization exception, so try it yourself After manually adding mapping_columns, the json file is imported and executed successfully ### What you expected to happen When verifying the accuracy of multiple tables of data quality, after maintaining the ON statement and other necessary configuration parameters on the front-end interface, the parameter mapping_columns can be correctly passed to the data quality task params json assembled in the back-end ### How to reproduce Test a multi-table accuracy case test and you will find the problem ### Anything else When configuring data quality rules again, basically each rule needs to configure local variables or global variables, otherwise it will report data quality task command: null, which is also an urgent problem to be solved  ### Version dev ### 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.
