javascript - 简单更新后 sails 无法升起

Question

我有一个在 aws elastic beanstalk 上运行的服务器。一切都很好。但是今天在应用更新时(绝对与所用模块的配置或版本控制无关)只是在网络应用程序的某些文本中添加了几个词(字面意思是“狗”这个词)。该应用程序开始崩溃并出现 502 nginx 网关错误。我认为这是因为该应用程序不活泼。我去恢复了更改(尽管我认为我不必这样做)。问题仍然存在。

尝试升起/启动 sails 应用程序时，我的输出如下。

    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!

这就是我在 package.json 中看到的内容，以备不时之需。

下面是validate-user-password.js

module.exports = {
  friendlyName: 'Validate user password (strict)',
  description: 'Strictly validate a string as the potential "password" for a user.',
  cacheable: true,
  sync: true,
  inputs: {
    string: {
      description: 'The string to validate as a password.',
      required: true,
      example: 'abcd1234',
    }
  },
  exits: {
    success: {
      description: 'The specified string is 100% valid.'
    },
    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
    // just skip this part.  (Also no need for the "notStrictlyValid" exit, output from the success exit,
    // or the `strict` input)
    //
    // n/a
    // Validate
    //////////////////////////////////////////////////////////////////////////////////////////////////////////

    // • Must be long enough.
    if (inputs.string.length < 7) {
      return exits.notValid(new Error('Password must consist of at least 7 characters.'));
    }

    // • Must not be too long.
    if (inputs.string.length > 72) {
      return exits.notValid(new Error('Password must not contain more than 72 characters.'));
    }

    return exits.success();
  }
};

确实，这可能是 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 ... */
}
