Wildfly-16 вызывает исключение нулевого указателя

Question

Я использую сервер wildfly16 в кластерном режиме с 3 узлами. Итак, в настоящее время моя настройка одноэлементной подсистемы - это политика простых выборов, но я хочу изменить ее на политику случайных выборов. Когда я меняю его на политику случайных выборов и перезапускаю, он перестает отображать развертывания в консоли управления и выдает исключение с нулевым указателем, но развертывания все еще выполняются.

Logs:

**ERROR [org.jboss.as.controller.management-operation] (ServerService Thread Pool -- 144) WFLYCTL0013: Operation ("read-attribute") failed - address: ([

Singleton Setting in domain.xml :
**<subsystem xmlns="urn:jboss:domain:singleton:1.0">
<singleton-policies default="default">
<singleton-policy name="default" cache-container="server">
<random-election-policy/>
</singleton-policy>
</singleton-policies>
</subsystem>**

If I am using simple-election-policy it deploys all deployments on one node only, So I want to shift deployments to other nodes.
