Parsed JSON object/hash requires a target configuration option

My cluster architecture is elk + Kafka + filebeat. Use the following configuration to parse JSON logs:

input {
    kafka {
       bootstrap_servers => "192.168.1.176:9092,192.168.1.178:9092,192.168.1.177:9092"
       client_id => "logstash175"
       auto_offset_reset => "latest"
       topics => "games"
       group_id => "games"
       reconnect_backoff_ms => 1000
       security_protocol => "SASL_PLAINTEXT"
       sasl_mechanism => "PLAIN"
       jaas_path => "/etc/logstash/kafka-client-jaas.conf"
       codec => json
    }
}

filter {
        if [service] == "daxuan_room_prod" {
            #mutate {
            #    gsub => [ "message", "\t", "" ]
            #    gsub => [ "message", "\n", "" ]
            #}
            json {
                skip_on_invalid_json => true
                source => "message"
                #target => "jsonmsg"
                remove_field => ["message"]
            }
        } else {
            json {
                skip_on_invalid_json => true
                source => "message"
        }
    }
}

output {
    if [service] {
       elasticsearch {
           hosts => ["192.168.1.74:9200","192.168.1.165:9200","192.168.1.166:9200"]
           user => "elastic"
           password => "SaOGLWt"
           ssl => true
           ssl_certificate_verification => true
           cacert => "/etc/logstash/ssl/root.pem"
           manage_template => false
           index => "%{[service]}-%{+YYYY.MM.dd}"

Numerous warnings after startup:

When I add the target configuration, the warning does not change. How do I fix it?
