kafka KRaft模式报：Invalid value test for configuration process.roles: String must be one of: broker, controller

我使用kafka 3.0.0的KRaft模式，安装kafka集群，报：

ERROR Exiting Kafka due to fatal exception (kafka.Kafka$)
org.apache.kafka.common.config.ConfigException: Invalid value test for configuration process.roles: String must be one of: broker, controller

错误详情：

我的server.properties配置如下：

process.roles=master

请问我该如何解决？
