### 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 1. Edit an **correct** MySql datasource (saved before and passed verification), and then click the "test connect" button, but can't connect the MySql datasource. See the part of "How to reproduce" for details. ### What you expected to happen 1. Edit an correct MySql datasource, and then click the "test connect" button, return to connect successfully. ### How to reproduce 1. Create an correct MySql datasource, and save. 2. **Restart the dolphinscheduler-api server. (must do this step)** 3. Edit the MySql datasource, and click the "test connect" button. 4. Connection failed ### Anything else 1. When edit an MySql datasource, the front-end page post a "test connect" request to the dolphinScheduler-api server. The request body that is object of BaseDataSourceParamDTO contains a null password field. 2. The object of BaseDataSourceParam will be verified before initializing the data source client. If the password is null a default password (123456) will to set. The verification code is [here](https://github.com/apache/dolphinscheduler/blob/4114cb07f64950f88ffb4aa8a4ecc4815f32d76b/dolphinscheduler-datasource-plugin/dolphinscheduler-datasource-api/src/main/java/org/apache/dolphinscheduler/plugin/datasource/api/client/CommonDataSourceClient.java#L71). ### 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.
