Detect invalid latitude and longitude values in an index

[Mateo_Loaiza_Rios]

I am trying to detect by means of a regular expression if the latitude and longitude fields are not valid, but it does not work for me. At this time the values of these 2 fields are string. I was trying to merge latitude and longitude to a single latlng field and then change to the geo_point data type to make queries based on latitude and longitude. Can someone help me with this?

Mapping fields

"latitude": {
            "type": "text",
            "fields": {
              "keyword": {
                "type": "keyword",
                "ignore_above": 256
              }
            }
          },"longitude": {
            "type": "text",
            "fields": {
              "keyword": {
                "type": "keyword",
                "ignore_above": 256
              }
            }
          },"latlng": {
            "type": "geo_point"
          }

Error example

This error is returned at the time of merging latitude and longitude to a single latlng type geo_point field
