I tried your configuration as follow for testing, i didn't get any error and i was able to view flow in SIEM without any issues:

    input {
      beats {
        port => 5044
      }
    }

    filter {
      if [destination][ip] =~ /^255\.255/ {
        mutate { 
			add_field => { "[destination][geo][city_name]" => "Casablanca" }
			add_field => { "[destination][geo][continent_name]" => "Africa" }
			add_field => { "[destination][geo][country_iso_code]" => "MO" }
			add_field => { "[destination][geo][country_name]" => "MOROCCO" }
			add_field => { "[destination][geo][region_iso_code]" => "AF-NO" }
			add_field => { "[destination][geo][region_name]" => "North Africa" }
			add_field => { "[destination][geo][name]" => "Casablanca Ain Diab Datacenter" }
			add_field => { "[destination][geo][location][lat]" => "33.56756115608338"}
			add_field => { "[destination][geo][location][lon]" => "-7.628037574169903"}
			}

        mutate {
				convert => ["[destination][geo][location][lat]", "float"]
				convert => ["[destination][geo][location][lon]", "float"]
				}
      }
    }

    output {
      elasticsearch {
        hosts => ["https://localhost:9200"]
        user => "elastic"
        password => "changeme"
        cacert => "/dev/es/elasticsearch/config/certs_ssl/node01/node01.crt"
        index => "%{[@metadata][beat]}-%{[@metadata][version]}-%{+YYYY.MM.dd}"
        action => "index"
		ssl => true
		pipeline => "geoip-info"
      }
    }
