MongoDB JSON验证未通过

我用验证器创建了一个非常基本的计数器集合。我还放了一个方法来调用它。在该方法中，我有一个findAndModify函数来更新序列。当我调用它时，只有当我将其级别更改为中等时，它才会通过验证程序。这里有什么问题

这是我的验证方案。

db.createCollection('counter', {
   validator: {
     $jsonSchema: {
       bsonType: 'object',
       required: ['sequence_value'],
       properties: {
         sequence_value: {
           bsonType: 'int'
         }
       }
     }
   }
 });

这是自动更新功能。

function getValueForNextSequence(sequenceOfName) {
    var sequenceDoc = db.counter.findAndModify({
        query: { _id: sequenceOfName },
        update: { $inc: { sequence_value: 1 } },
        new: true
    });
    return sequenceDoc.sequence_value;
}

db.user.insert({
    _id: getValueForNextSequence("user_id"),
    name: "Heggo",
    surname: "Ruffo",
    phone: "5879885858",
    roles: ["Logistic"],
    password: "d1e8a70b5ccab1dc2f56bbf7e99f064a660c08e361a35751b9c483c88943d082"
})

        "ok" : 0,

这是我要插入调用的shell命令。

function getValueForNextSequence(sequenceOfName) {
    var sequenceDoc = db.counter.findAndModify({
        query: { _id: sequenceOfName },
        update: { $inc: { sequence_value: 1 } },
        new: true
    });
    return sequenceDoc.sequence_value;
}

db.user.insert({
    _id: getValueForNextSequence("user_id"),
    name: "Heggo",
    surname: "Ruffo",
    phone: "5879885858",
    roles: ["Logistic"],
    password: "d1e8a70b5ccab1dc2f56bbf7e99f064a660c08e361a35751b9c483c88943d082"
})

和输出日志…
