kafka报Invalid security protocol `PLAINTEXT1` defined in listener.security.protocol.map

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 security protocol PLAINTEXT1 defined in listener.security.protocol.map

错误详情：

我的server.properties配置如下：

listeners=PLAINTEXT://172.21.0.1:9092
advertised.listeners=PLAINTEXT1://172.21.0.1:9091
listener.security.protocol.map=PLAINTEXT:PLAINTEXT1

请问我该如何解决？
