在dynamoose上更新ValidationException：键上的条件数无效

Question

下午好

动态模式更新会引发ValidationException错误：键上的条件数无效。我尝试过调试，这是导出DEBUG = dynamoose *

的调试结果

dynamoose:model Update {"key":"1","email":"biraj@gmail.com"} +24s
  dynamoose:attribute toDynamo {"S":"1"} +24s
  dynamoose:attribute toDynamo {"N":"1550997177674"} +2ms
  dynamoose:attribute toDynamo {"N":"1550997177674"} +2ms
  dynamoose:table Waiting for Active table, Chat, {"update":true,"create":true,"waitForActive":true,"waitForActiveTimeout":180000,"prefix":"","suffix":""} +24s
  dynamoose:table Waiting... +4ms
  dynamoose:table index idGlobalIndex.IndexStatus is ACTIVE +22ms
  dynamoose:model updateItem { TableName: 'Chat',
  Key: { key: { S: '1' }, initiate_time: null },
  ExpressionAttributeNames: { '#_n0': 'update_time' },
  ExpressionAttributeValues: { ':_p0': { N: '1550997177674' } },
  ReturnValues: 'ALL_NEW',
  UpdateExpression: 'SET #_n0 = :_p0 ' } +34ms 

这是执行时返回的错误：

以下是正在执行操作的聊天模式：

var dynamoose = require('dynamoose');

var ChatSchema = new dynamoose.Schema({
  id:{
    type: String,
    index: {
      global:true
    }
  },
  key: {
    type: String,
    hashKey: true,
    default:"1"
  },
  category_id: {
    type: String
  },
  initiate_time: {
    type: Date,
    rangeKey: true
  },
  update_time: {
    type: Date,
    index: {
      global: false,
      name:"UpdateTimeSecondaryIndex"
    }
  },
  name: {
    type: String
  },
  email: {
    type: String,
    index: {
      global: false
    }
  },
  support_id: {
    type: String
  }

});

ChatSchema.method('getLanguages', async function () {
    var {ChatLang} = require("./index");
    var languages = await ChatLang.query({chatId: this.id}).exec();
    if (languages != null && languages.length > 0)
    {
      return languages;
    }
    return false;
});


module.exports = ChatSchema;

这是实际的更新代码：

try {
      await Chat.update({
        key: "1",
        email: args.chat.email
      }, {
          update_time: Moment().subtract(24, "hours"),
          initiate_time: Moment().subtract(24, "hours")
        });
    } catch (err) {
      console.log(err);
    }

感谢您提供任何线索和帮助。
