在我的 routes.json 中定义的一些自定义端点上调用 DELETE 时遇到了几个问题

我有一些看起来像这样的数据 -

{
  "apps": [
    {
      "creation_time": "2018-06-07 15:56:01",
      "description": "Test App",
      "id": "2",
      "name": "Test",
      "update_time": "2018-06-07 15:56:01"
    },
  ],
  "account_types": [
    {
      "app": {
        "description": "Test app",
        "id": "2",
        "name": "Test",
        "user_id": "337"
      },
      "creation_time": "2018-06-07 16:00:31",
      "description": "Regular Test account type",
      "id": "2",
      "max": "None",
      "name": "BASIC",
      "update_time": "2018-06-07 16:00:31"
    },
    {
      "app": {
        "description": "Test app",
        "id": "2",
        "name": "Test",
        "user_id": "337"
      },
      "creation_time": "2018-08-02 13:48:45",
      "description": "Premium Test account type",
      "id": "8",
      "max": "None",
      "name": "PREMIUM",
      "update_time": "2018-08-02 13:48:45"
    }
  ]
}

这是我的 routes.json

{
    "/test/:app_id/accounts/type": "/account_types?app.id=:app_id",
    "/test/:app_id/accounts/type/:type_id": "/account_types?app.id=:app_id&id=:type_id"
}

这是输出

  \{^_^}/ hi!

  Loading mock-data/apps.json
  Loading routes.json

  Resources
  http://localhost:3000/apps

  Other routes

  /test/:app_id/accounts/type/:type_id -> /account_types?app.id=:app_id&id=:type_id

  Watching...

GET /account_types?app.id=2&id=2 200 85.703 ms - 334
GET /account_types?app.id=2&id=4 200 81.023 ms - 2
GET /account_types?app.id=2&id=8 200 38.714 ms - 336
DELETE /account_types?app.id=2&id=8 404 26.290 ms - 2

这就是我运行 json-server 的方式

json-server --watch mock-data/apps.json -r routes.json

当我在这两个端点上调用 GET 时，我检索到了正确的信息，但是当我在它们上调用 DELETE 时，我收到状态码 404，是我做错了什么还是这是一个已知问题？

任何帮助，将不胜感激
