Realm Device Sync Won’t Perform the Query using KMM

Hi,

I’m currently using Kotlin Multiplatform and Device Sync to access my Realm collections. However, my queries don’t seem to reach the server when I query an object using the ObjectId :

java.util.NoSuchElementException: List is empty.
at kotlin.collections.CollectionsKt___CollectionsKt.first(_Collections.kt:221)
at data.realm.RealmDB.getRecommendation(RealmDB.kt:102)

I recently upgraded my project to Kotlin 2.0, so I use realm version to 2.0.0 as well.

Here is what my data class looks like :

@Serializable
class Recommendation: RealmObject {
    @PrimaryKey
    @PersistedName("_id")
    var id: ObjectId = ObjectId()
    var name: String = ""
    var products: RealmList<String> = realmListOf()
    companion object
}

My Realm object configuration :

    init {
        runBlocking {
            user = app.login(Credentials.anonymous())
        }
        configureRealm()
    }

    private fun configureRealm() {
        val config = SyncConfiguration.Builder(
            user = user,
            schema = schemaClasses
        ).schemaVersion(0)
            .initialSubscriptions() {
                add(it.query<Recommendation>())
                add(it.query<data.models.User>("_id == $0", ObjectId(user.id)))
            }
            .build()

        realm = Realm.open(config)
    }

The performed query to my collection. I hard coded the ID for testing :

    override fun getRecommendation(id: ObjectId): Recommendation {
        println("Performing query for recommendation with id: $id")
        return realm.query<Recommendation>("_id == $0", ObjectId("66db33beb29eaf61e4e4988b")).find().first()
    }

and finally my JSON table :

[{
  "_id": {
    "$oid": "66db33beb29eaf61e4e4988b"
  },
  "name": "picksOfTheMonth",
  "products": [ ...]
}]

Just in case, my gradle configuration :

library-base = { module = "io.realm.kotlin:library-base", version= "2.0.0" }
library-sync = { module = "io.realm.kotlin:library-sync", version= "2.0.0" }
kotlinx-coroutines-core = { module = "org.jetbrains.kotlinx:kotlinx-coroutines-core", version.ref = "1.8.0" }

     commonMain.dependencies { // Realm
            implementation(libs.library.base)
            implementation(libs.library.sync) 
            implementation(libs.kotlinx.coroutines.core)
     }

It seems to me like there might be something missing with the way I configured the Realm. When I used the version 1.16.0 I was able to make it sync without any problem.

I really appreciate your help in advance !
