Elastic Search: ES-PHP Client how to create GEOPOINT Index - elasticsearch

Question

I am trying to create an index that should contain GEOPoint by using the Elastic Search PHP client -> https://www.elastic.co/guide/en/elasticsearch/client/php-api/5.0/index.html
My Code is as follow
$params = [
'index' => 'sweden_codes',
'type' => 'sweden_c',
'body' => [
'mappings' => [
'location' => [
'properties' => [
'pin' => [
'properties' => [
'location' => [
'type' => 'geo_point'
]
]
]
]
],
'text' => $code->City,
'pin' => [
'location' => [
'lat' => $code->Latitude,
'lon' => $code->Longitude
]
]
]
]
];
$client = ClientBuilder::create()
->setSSLVerification(false)
->setHosts(["elasticsearch:9200"])->build();
The Problem is when i go into kibana it say " No Compatible Fields: The "sweden_codes" index pattern does not contain any of the following field types: geo_point"
can anyone please have a look into the issue and let me know whats wrong with my mapping and index creation
Here is the Code for Mappings that works for me
$params = [
'index' => 'sweden_postal_codes',
'body' => [
'mappings' => [
'codes' => [
'properties' => [
'location' => [
'type' => 'geo_point'
],
'city' => [
'type' => 'string'
]
]
]
]
]
];
$client = ClientBuilder::create()
->setSSLVerification(false)
->setHosts(["elasticsearch:9200"])->build();
// Adding the index into the ES Cluster
$response = $client->indices()->create($params);
Here is the code for document indexing that worked for me
$params = [
'index' => 'sweden_postal_codes',
'type' => 'codes',
'id' => 2,
'body' => [
'location' => [
'lat' => 30.5268956,
'lon' => 79.2289643
],
'city' => 'Stockholm'
]
];
$client = ClientBuilder::create()
->setSSLVerification(false)
->setHosts(["elasticsearch:9200"])->build();
// Adding the index into the ES Cluster
$response = $client->index($params);
