### 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 Randomly, we get "task instance host is null" error when we try to run the workflow. This happens when the host is null in the server object. This is generally solved by restarting the server. ### Use case If the host is not available, it should not be selected as a host. We should create a list where the host is not null before randomly selecting a host. The issue is traced back to the RegistryClient.getRandomServer method implementation. It is used by /executor/execute, /executor/start-workflow-instance endpoints. ### Related issues https://github.com/apache/dolphinscheduler/issues/13776 ### Are you willing to submit a 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.
