ExtJs：console在测试版本中返回无法识别的别名：data.validator.presence

Question

我在运行应用程序构建测试并运行测试版本后使用extjs 6.2创建应用程序，控制台返回错误：

  

未捕获错误：[Ext.createByAlias]无法识别的别名：data.validator.presence

我知道这与我的登录页面的模型有关，但我不知道如何解决这个问题。

登录页面：

登录验证模型

Ext.define('uber.model.User',{
    extend: 'Ext.data.Model',
    alias: 'model.user',

    fields: [

        { name: 'username', type: 'string' },
        { name: 'password', type: 'string' }        
    ],

    validators: {
        username: { type: 'presence', message: 'please input valid username' },
        password: { type: 'presence', message: 'please input valid password' }
    }
})

非常感谢一些帮助
