Azure CosmosDB MongoDB Api GeoSpatial queries not working

Question

I have CosmosDB MongoDB-API instance.
Mongo server version = 4.0.0
Inserted documents look like:

  {
    "_id": "111",
    "fileName": "some.txt",
    "type": "ONE",
    "location": {
        "type": "MultiPoint",
        "coordinates": [
            [4, 4]
        ]
    },
    "aPoint": {
        "type": "Point",
        "coordinates": [4, 4]
    }
}

I created geo spatial indexes with mongosh(also I've tried with MongoDB Compass):

db.coll.createIndex({ location: "2dsphere" })
db.coll.createIndex({ aPoint: "2dsphere" })

result of db.coll.getIndexes()

[
  {
    v: 1,
    key: { _id: 1 },
    name: '_id_',
    ns: 'ns_name.coll'
  },
  {
    v: 1,
    key: { location: '2dsphere' },
    name: 'location_2dsphere',
    ns: 'ns_name.coll'
  },
  {
    v: 1,
    key: { aPoint: '2dsphere' },
    name: 'aPoint_2dsphere',
    ns: 'ns_name.coll'
  }
]

I have tried a lot of queries:

db.coll.find( { "aPoint": { $nearSphere : [ 4, 4 ], $maxDistance: 1000 } } )  
db.coll.find( { "aPoint.coordinates": { $nearSphere : [ 4, 4 ], $maxDistance: 1000 } } )      
db.coll.find({aPoint : { $nearSphere:{ $geometry: { type: "Point", coordinates: [4, 4] }, $maxDistance: 1000 }}} )  
db.coll.find({"aPoint.coordinates": { $nearSphere:{$geometry:{ type: "Point", coordinates: [4, 4]}, $maxDistance: 1000 }}})
  
db.coll.find({ "location": { $nearSphere : [ 4, 4 ], $maxDistance: 1000 }})  
db.coll.find({ "location.coordinates": { $nearSphere : [ 4, 4 ], $maxDistance: 1000 }})  
db.coll.find({location: { $nearSphere:{ $geometry: { type: "Point", coordinates: [4, 4] }, $maxDistance: 1000 }}} )  
db.coll.find({"location.coordinates":{$nearSphere:{ $geometry:{ type:"Point",coordinates:[4, 4]}, $maxDistance:1000 }}})  

But none of them works. The result is empty.
Do you know how I can make it work for Azure CosmosDB?
Thank you in advance.
