架构验证失败 - Mongo db atlas 设备同步

Question

我想在我的应用程序中使用 Mongo DB 的 Atlas 设备同步功能。我在我的 Kotlin 代码中建模了一个 BankAccount 类，如下所示。

open class BankAccount: RealmObject, Searchable {

    @PrimaryKey
    var _id: ObjectId = ObjectId()

    var accountHolderName: String = ""

    var accountNumber: String = ""

    var accountType: String = ""

    var bankName: String = ""

    var cardCvv: String = ""

    var cardNo: String = ""

    var cardPin: String = ""

    var expiryDate: String = ""

    var haveBankingApp: Boolean = false

    var haveCard: Boolean = false

    var haveUpi: Boolean = false

    var ifscCode: String = ""

    var isArchived: Int = 0

    var loginPin: String = ""

    var nameOnCard: String = ""

    var ownerId: String = ""

    var regEmail: String = ""

    var regMobNo: String = ""

    var remarks: String = ""

    var transactionPin: String = ""

    var upiPin: String = ""

    override fun doesMatchSearchQuery(query: String): Boolean {
        return bankName.contains(query.trim(), ignoreCase = true) || accountHolderName.contains(query.trim(), ignoreCase = true)
    }
}

我的 JSON 架构如下所示：

{
  "title": "BankAccount",
  "properties": {
    "_id": {
      "bsonType": "objectId"
    },
    "ownerId": {
      "bsonType": "string"
    },
    "bankName": {
      "bsonType": "string"
    },
    "accountHolderName": {
      "bsonType": "string"
    },
    "accountType": {
      "bsonType": "string"
    },
    "accountNumber": {
      "bsonType": "string"
    },
    "ifscCode": {
      "bsonType": "string"
    },
    "regMobNo": {
      "bsonType": "string"
    },
    "regEmail": {
      "bsonType": "string"
    },
    "remarks": {
      "bsonType": "string"
    },
    "haveCard": {
      "bsonType": "bool"
    },
    "nameOnCard": {
      "bsonType": "string"
    },
    "cardNo": {
      "bsonType": "string"
    },
    "expiryDate": {
      "bsonType": "string"
    },
    "cardCvv": {
      "bsonType": "string"
    },
    "cardPin": {
      "bsonType": "string"
    },
    "haveUpi": {
      "bsonType": "bool"
    },
    "upiPin": {
      "bsonType": "string"
    },
    "haveBankingApp": {
      "bsonType": "bool"
    },
    "loginPin": {
      "bsonType": "string"
    },
    "transactionPin": {
      "bsonType": "string"
    },
    "isArchived": {
      "bsonType": "int"
    }
  },
  "required": [
    "_id",
    "ownerId",
    "bankName",
    "accountHolderName",
    "accountType",
    "accountNumber",
    "ifscCode",
    "regMobNo",
    "regEmail",
    "remarks",
    "haveCard",
    "nameOnCard",
    "cardNo",
    "expiryDate",
    "cardCvv",
    "cardPin",
    "haveUpi",
    "upiPin",
    "haveBankingApp",
    "loginPin",
    "transactionPin",
    "isArchived"
  ]
}

一切都很完美。我已启用设备同步，以正确的方式正确设置权限，并完美配置 Mongo DB 领域，但我仍然不断收到主键的此错误:(

抑制：kotlinx.coroutines.DiagnosticCoroutineContextException： [StandaloneCoroutine{取消}@5b935b7，Dispatchers.Main.immediate] 引起原因：java.lang.IllegalStateException： [RLM_ERR_SCHEMA_VALIDATION_FAILED]：架构验证失败，原因是 出现以下错误： - 同步 Realm 上必须有一个名为“_id”的主键属性，但未找到“BankAccount”类型的主键属性
