Empty result in MongoCollection.find

MongoDB Atlas App Services & Realm
,

Hi, i’m creating a query via realm android, but the only one result that is fetched is collection.count(). Trying to retrieve data or a list of data return always null.

This is the code that query database

CoroutineScope(Dispatchers.IO).launch {
            val res: Deferred<Tenant> = async {
                val mongoDatabase = loginRealm().getMongoClient("mongodb-atlas")
                    .getDatabase(BuildConfig.MONGODB_DATABASE)

                val codecRegistry = CodecRegistries.fromRegistries(
                    AppConfiguration.DEFAULT_BSON_CODEC_REGISTRY,
                    CodecRegistries.fromProviders(
                        PojoCodecProvider.builder().automatic(true).build()
                    )
                )

                val collection = mongoDatabase.getCollection(
                    Tenant::class.java.simpleName,
                    Tenant::class.java
                ).withCodecRegistry(codecRegistry)
               // return numbers of documents. Ok
                val count = collection.count().get()

                Log.d("REALM_COUNT", count.toString())
               // Return null. Not ok
                collection.findOne(Document("_id", id)).get()
            }

This is realm backend log:
