Hi I cannot see the difference between the two configurations, but the error info `Failure executing: POST at: https://*/k8s/clusters/c- fwkxh/apis/apps/v1/namespaces/test-flink/deployments. Message: Deployment.apps "basic-example" is invalid` is strange. Maybe you can check whether the configuration of k8s has changed?
