How to convert existing coordinates in ElasticSearch to geopoints - elasticsearch

Question

I am trying to convert latitude and longitude to geo_points in ElasticSearch. The problem is, I already have the data uploaded latitude and longitude values in elasticsearch but am having trouble converting them. I am getting the feeling that there is a solution using painless, but haven't quite pinpointed it.
This is what the mapping looks like
{
"temporary_index" : {
"mappings" : {
"handy" : {
"properties" : {
"CurrentLocationObj" : {
"properties" : {
"lat" : {
"type" : "float"
},
"lon" : {
"type" : "float"
}
}
},
"current_latitude" : {
"type" : "text",
"fields" : {
"keyword" : {
"type" : "keyword",
"ignore_above" : 256
}
}
},
"current_longitude" : {
"type" : "text",
"fields" : {
"keyword" : {
"type" : "keyword",
"ignore_above" : 256
}
}
},
"location" : {
"type" : "geo_point"
},
}
}
}
}
}
And this is what a sample doc looks like
"hits" : [
{
"_index" : "temporary_index",
"_type" : "handy",
"_id" : "9Q8ijmsBaU9mgS87_blD",
"_score" : 1.0,
"_source" : {
"current_longitude" : "139.7243101",
"current_latitude" : "35.6256271",
"CurrentLocationObj" : {
"lat" : 35.6256271,
"lon" : 139.7243101
}
There are obviously more fields, but I have removed them for the sake of clarity.
This is what I have tried.
POST temporary_index/_update_by_query
{
"query": {
"match_all": {}
},
"script": {
"inline": "ctx._source.location = [ctx._source.current_latitude, ctx._source.current_longitude]",
"lang": "painless"
}
}
However I get the following error:
"reason": "failed to parse field [location] of type [geo_point]",
"caused_by": {
"type": "parse_exception",
"reason": "unsupported symbol [.] in geohash [35.4428348]",
"caused_by": {
"type": "illegal_argument_exception",
"reason": "unsupported symbol [.] in geohash [35.4428348]"
}
}
I have used the following stackoverflow as a basis for my solution, but I am clearly doing something wrong. Any advice is helpful! Thanks.

Great start! You're almost there.
Just note that when specifying a geo_point as an array, the longitude must be the first element and the latitude comes next. However, I suggest you do it like this instead and it will work:
POST temporary_index/_update_by_query
{
"query": {
"match_all": {}
},
"script": {
"inline": "ctx._source.location = ['lat': ctx._source.current_latitude, 'lon': ctx._source.current_longitude]",
"lang": "painless"
}
}
