我尝试使用logstash 7.6.1来记录我的f5 waf/asm，当我尝试从我的f5远程日志收集一些日志时，我从我的elk服务器运行logstash -f f5.config。它说这句话并循环：
[[main]> worker 1]错误-分析KV时出现异常{：exception=>“Invalid FieldReference：`info tmm 2 [16492]：Rule /Common/myrule：source logreq：/mywebsitepath/"}
那么这里有什么问题以及如何解决呢？
这是我的f5.config：

input {
  syslog {
    port => 5144
  }
}
filter {
  kv {
    field_split => ","
  }
  mutate {
    split => { "attack_type" => "," }
    split => { "sig_ids" => "," }
    split => { "sig_names" => "," }
    split => { "sig_cves" => "," }
    split => { "staged_sig_ids" => "," }
    split => { "staged_sig_names" => "," }
    split => { "staged_sig_cves" => "," }
    split => { "threat_campaign_names" => "," }
    split => { "staged_threat_campaign_names" => "," }
    split => { "violations" => "," }
    split => { "sub_violations" => "," }
  }
  geoip {
    source => "ip_client"
  }
}
output {
  elasticsearch {
    hosts => ['myip:9200']
    index => "waf-logs-%{+YYY.MM.dd}"
  }
}
