NumberFormatException[For input string] Elastic Search

Question

I am trying to send a geopolygon filter to Elastic Search. It expects lat/long sets as numbers. But when I try to make that combination through loops, I am unable to to create it and constantly getting NumberFormatException[For input string. Here is the code I am trying.

    $points = $this->input->post('points');
    $points_to_pass = array();
    foreach ($points as $point) {
        $splits = explode(",", $point);

        $points_to_pass[] = [$splits[1],$splits[0]];
    }
    $json = [
        'query' => [
            'bool' => [
                'must_not' => [
                    ['terms' => ['_id' => []]],
                    ['terms' => ['rarity' => []]]
                ],
                'must' => [
                    'range' => [
                        'disappearTime' => [
                            'gte' => 'now',
                            'lte' => 'now+1d'
                        ]
                    ]
                ],
                'filter' => [
                    ['term' => ['pokemon_id' => 16]],
                    [
                        'geo_bounding_box' => [
                            'location' => [
                                'top_left' => [
                                    'lat' => 52.280577919216356,
                                    'lon' => -113.78533601760866
                                ],
                                'bottom_right' => [
                                    'lat' => 52.26306210545918,
                                    'lon' => -113.81855249404909
                                ]
                            ]
                        ]
                    ],
                    [
                        'geo_polygon' => [
                            'location' => [
                                "points" => [
                                    $points_to_pass
                                ]
                            ]
                        ]
                    ]
                ]
            ]
        ]
    ];

Whereas if I put hard coded values it works perfectly. Working example of hard coded values is as follows.

    $json = [
        'query' => [
            'bool' => [
                'must_not' => [
                    ['terms' => ['_id' => []]],
                    ['terms' => ['rarity' => []]]
                ],
                'must' => [
                    'range' => [
                        'disappearTime' => [
                            'gte' => 'now',
                            'lte' => 'now+1d'
                        ]
                    ]
                ],
                'filter' => [
                    ['term' => ['pokemon_id' => 16]],
                    [
                        'geo_bounding_box' => [
                            'location' => [
                                'top_left' => [
                                    'lat' => 52.280577919216356,
                                    'lon' => -113.78533601760866

                ]
            ]
        ]
    ];

How can I convert the $points_to_pass in a format that is accepted by ElasticSearch.

thanks

Answer 1

Since $points_to_pass is already an array of arrays, you should try like this:

                [
                    'geo_polygon' => [
                        'location' => [
                            "points" => $points_to_pass
                        ]
                    ]
                ]
