Elastic Stack Logstash

what could be wrong with this particular config?
i have multiple configs just like this and everything is working except this one

input {
    file {
        path => [ "${LL_LOG_IMPORT_NGINX:/var/log/remote/ingress-nginx/nginx-access.log}" ]
        type => "nginx"
        sincedb_path => "${LL_SINCEDB_IMPORT_NGINX:/var/lib/logstash/plugins/inputs/file/nginx-import.sincedb}"
    }
}
filter {
    if [type] == "nginx" {
        grok {
          match => {
             "message" => "%{TIMESTAMP_ISO8601:loggedtime} %{IPORHOST:host } %{PROG:program}(?:\[%{POSINT:pid}\])?: %{HTTPD_COMBINEDLOG}"
          }
        }
       date {
           locale => "en"
           match => [ "timestamp", "MMM dd yyyy HH:mm:ss", "MMM  d yyyy HH:mm:ss", "dd/MMM/yyyy:HH:mm:ss Z", "ISO8601" ]
       }
       geoip {
           source => "clientip"
       }
       useragent {
           source => "agent"
           prefix => "useragent_"
       }
       mutate {
           convert => { "bytes" => "integer" }
       }
    }
}
output {
    elasticsearch {
        hosts => ["http://localhost:9200"]
        index => "logstash-%{type}-%{+YYYY.MM}"
    }
}
