@divine thanks for replying.
As the latest version was not working. Now I used "jenssegers/mongodb": "^4" and updated the composer but same problem.
I have mongodb --version v3.6.3
This is the error I am getting
Can't extract geo keys: { _id: ObjectId('5f868fd3da8d1f75472157a2'), property_name: "Galwan House", user_id: 30, property_slug: "galwan-house", property_address_line_1: "dhdfhr", property_address_line_1_ar: null, property_address_line_2: null, property_address_line_2_ar: null, property_nearest_landmark: "dfhfd", property_nearest_landmark_ar: null, property_country: "India", property_state: "West Bengal", property_zipcode: "700063", property_location: { type: "Poin---134

I have created the schema as
$table->index(['property_location' => '2dsphere']);
The way I am inserting the data is

$property->property_location = ["type" => "Point", "coordinates" => [$request->lng, $request->lat]];
$property->save();

what I am doing wrong?

Thanks in advance !!
