&引用；迭代器不提供'；投掷'；方法。”；在Foreach node.js中

我在使用nodejs生成器时遇到问题，当我启动代码时，出现以下错误：

node:3632) UnhandledPromiseRejectionWarning: Unhandled promise rejection (rejection id: 1): TypeError: The iterator does not provide a 'throw' method.
(node:3632) [DEP0018] DeprecationWarning: Unhandled promise rejections are deprecated. In the future, promise rejections that are not handled will terminate the Node.js process with a non-zero exit code.

代码如下，我使用AdoniJs。User.all和User.typeModule都是数据库关系

// This is the function that is called at the defined schedule
  * handle () {
    const usersWrapper = yield User.all()
    yield * usersWrapper.map(function * (user) {
      const typeModulesWrapper = yield user.typeModule()
      typeModulesWrapper.map(function (module) {
        const Controller = use(module.controller_path)
        Controller.event()
      })
    })
  }
}

多谢各位
