I need to convert 2 Fields (doc.geoLat and doc.geoLong) to geopoint datatype.  
I tried the following but it dosen't work

Could you please show me where I might be making a mistake

```auto
      if [type] == \"xxxxx\" {

          mutate {
            add_field => {
              \"location\" => [\"%{[lat]}\",\"%{[lon]}\"]
            }
          }
          
          mutate {
            convert => {
              \"location\" => \"float\"
            }
          }
        
  mutate {
    copy => {
      \"[doc][geoLat]\" => \"[location][lat]\"
      \"[doc][geoLong]\" => \"[location][lon]\"
    }
  }

```

Kibana does show me a geopoint field (location) once this executes but no data is being copied ( ialso tried mutate \> rename
