amazon-web-services - 无服务器框架不是通过配置在 AWS 上部署 API 网关

Question

我正在尝试使用无服务器框架创建一个 Lambda，当客户端连接到 websocket API 网关时调用它。 AWS CloudFormation 正在创建已定义但未创建 websocket API 网关的 Lambda 函数。

在尝试编写自己的(不起作用)之后，我将我在无服务器文档中找到的示例复制并粘贴到新创建的无服务器文件夹中，只是为了看看它是否可以工作 - 它没有，我可以找不到其他似乎有类似问题的人。

到目前为止，我已经尝试了此处记录的简单和扩展方法(这是示例代码所基于的方法):
https://serverless.com/framework/docs/providers/aws/events/websocket/

而且我也尝试关注这个博客，这也导致了 Lambda 的创建，但没有创建 API 网关。
https://serverless.com/blog/api-gateway-websockets-example/

这是我的 serverless.yml 文件。除了 API 网关之外，它按照我的预期进行部署:

service: temp
provider:
  name: aws
  runtime: nodejs8.10
  region: eu-west-2

functions:
  default:
    handler: handler.connect
    events:
      - websocket: 
        route: $default

这是无服务器部署 -v 输出:

如果有人能对此有所了解，因为我可能完全遗漏了一些明显的东西，我将不胜感激。

我遇到了完全相同的问题，对我来说，解决方案是像这样正确缩进 route:

functions:
  default:
    handler: handler.connect
    events:
      - websocket: 
          route: $default

所以基本上改变:

- websocket: 
  route: $default

至:

- websocket: 
    route: $default
