Non-Integer Data Types in my Data... How to make a Visualization?

Elastic Stack Kibana
10

Following Alex's suggestion, I decided to go for broke and tried implementing a Index Template. "logstash-2019.08.08-000001" is the name of my Index:

curl -X PUT "localhost:9200/_template/logstash-2019.08.08-000001" -H 'Content-Type: application/json' -d'
{
    "template": "logstash-2019.08.08-000001",
    "order": 1,
        "settings": {
            "index": {
            "refresh_interval": "5s"
            }
        },
    "mappings": {
        "default": {
            "_all": {
                "norms": false,
                "enabled": true
                },
                "properties": {
                    "Packet.L3.Src": { "type": "ip"},
                    "Packet.L3.Dst": { "type": "ip"}
            }
        }
    }
}
'

FYI, this was run directly on the command line within my ElasticSearch Docker container (v7.3.0) The error message I got back was a single run-on error message, I've added a bunch of newlines to try and make sense of it:

{"error":{
		"root_cause":[
			{
					"type":
						"mapper_parsing_exception",
						"reason":"Root mapping definition has unsupported parameters:  
							[default : 
								{_all={norms=false, enabled=true}, 
								properties={Packet.L3.Src={type=ip}, 
								Packet.L3.Dst={type=ip}}}]"}],
								"type":"mapper_parsing_exception","reason":"Failed to parse mapping [_doc]: 
								Root mapping definition has unsupported parameters:  
								[default :
								{_all={norms=false, enabled=true}, 
								properties={Packet.L3.Src={type=ip}, 
								Packet.L3.Dst={type=ip}}}]",
								
								"caused_by":{
								"type":"mapper_parsing_exception",
								"reason":"Root mapping definition has unsupported parameters:  
								[default : 
								{_all={norms=false, enabled=true}, 
								properties={Packet.L3.Src={type=ip}, Packet.L3.Dst={type=ip}}}]"}},
	"status":400
}

Maybe I'm misreading this, but it looks like Elasticsearch is telling me, "I don't see a Packet.L3.Src" or "Packer.L3.Dst" field within logstash-2019.08.08-000001 Am I missing the biggest picture?

Thanks
