我有一个运行在aws弹性beanstalk上的服务器。它一切都很好。但今天在应用更新时（绝对与所使用的模块的配置或版本无关），这只是在网络应用程序中的某些文本中添加了几个单词（字面意思是“狗”＃39;）。应用程序因502 nginx网关错误而崩溃。我认为这是因为该应用程序不是在冒充。我去了并改变了改变（虽然我不认为我必须这样做）。问题仍然存在。
尝试提升/启动风帆应用程序时的输出如下：
Failed to load helper `web/auth/validate-user-password` as a machine!
A hook (`helpers`) failed to load!
Failed to lift app: ImplementationError: Sorry, could not interpret "web/auth/validate-user-password" because its underlying implementation has a problem:
------------------------------------------------------
• The `cacheable` property is no longer supported. (Please use `sideEffects: 'cacheable' instead.)
------------------------------------------------------
If you are the maintainer of "web/auth/validate-user-password", then you can change its implementation to solve the problem above. Otherwise, please file a bug report with the maintainer, or fork your own copy and fix that.

(You are seeing the above error message because no custom callback was programmatically provided to `.lift()`.)
A hook (`orm`) failed to load!
这是我在package.json中看到的，以防它有用。

及以下是validate-user-password.js

sync: true,
inputs: {

},
notValid: {
description: 'The specified string is not a valid password.'
},
},
fn: function (inputs,exits) {
// Coerce
//////////////////////////////////////////////////////////////////////////////////////////////////////////
// Since we don't need to support `strict: false` for this validator (it is ALWAYS strict), then we can

}
return exits.success();
}
};
答案 0 :(得分：0)
实际上，它可能是Sails本身的更新导致的。您是否为validate-user-password.js尝试了以下配置？
module.exports = {
friendlyName: 'Validate user password (strict)',
description: 'Strictly validate a string as the potential "password" for a user.',
sideEffects: 'cacheable',
sync: true,
/* ... rest of content ... */
}
答案 1 :(得分：0)
我想知道问题是否与Sails核心使用的data () {
return {
items: []
}
},
版本中的这次更改有关。除非手动增加了Sails依赖项的语义版本范围（SVR），否则这通常不会影响您的应用程序。但是由于此应用使用的是Sails v1的预发布版本，因此很可能是此更改在下游获得的原因。
如@Alexis N-o所述，解决方案是使用以下方法代替使用machine：
cacheable: true
