rsyslog推向kafka，一直报错？

报错信息：

rsyskig配置文件：
ruleset(name="nginx-kafka") {
    #日志转发kafka
    action (
        type="omkafka"
        # template="nginxAccessTemplate"
        confParam=["compression.codec=snappy", "queue.buffering.max.messages=4000000"]
        # partitions.number="4"

}
 
请问一下是什么配置导致的？
