Geo_distance query - illegal latitude value that isn't the latitude I sent

[ndtreviv (Nathan Trevivian)]

I'm getting some odd behaviour when doing geo_distance queries via the Rest High Level API on elasticsearch v6.2.4.

For example, my query is this:

{
  "from":0,
  "size":20,
  "query": {
    "bool": {
      "must": [{
        "geo_distance": {
          "location":[34.06388166666667,-118.358675],
          "distance":1.0,
          "distance_type":"arc",
          "validation_method":"STRICT",
          "ignore_unmapped":false,
          "boost":1.0
        }
     }],
     "adjust_pure_negative":true,
     "boost": 1.0
    }
  },
  "explain":false,
  "_source":{"includes":[],"excludes":[]}
}

But it responds with this as the root_cause:

"type":"query_parsing_exception",
"reason":"illegal latitude value [264.375] for [geo_distance]"

What's happening here? That is not the latitude I queried with, as you can see.

Any help is much appreciated.

Update: I also notice that in the query the values are presented as [lon,lat] rather than [lat,lon]. I'm using the QueryBuilder correctly:

                    QueryBuilders.geoDistanceQuery(LOCATION_FIELD)
                            .point(lat, lon)
                            .distance(distance, unit)
                            .geoDistance(geoDistance));

According to the point method in the builder:

    public GeoDistanceQueryBuilder point(double lat, double lon) {
    ...

Turns out that this was because my proxy node was pointing at an older version of elasticsearch. The error doesn't make much sense, but there you go.
