What is the correct response format for apply the patch?

I have config:

{
  "templates": {
    "main": {
      "type": "container",
      "height": {
        "type": "match_parent"
      },
      "visibility_action": {
        "log_id": "load_data",
        "url": "div-action://download?url=http://example.com/patch",
        "visibility_duration": 1,
        "visibility_percentage": 1
      }
    }
  },
  "card": {
    "log_id": "card",
    "states": [
      {
        "div": {
          "type": "main",
          "id": "main",
          "items": [
            {
              "type": "text",
              "id": "wellcome",
              "text": "wellcome"
            }
          ]
        },
        "state_id": 0
      }
    ]
  }
}

http://example.com/patch:

{
  "changes": [
    {
      "id": "main",
      "items": [
        {
          "type": "text",
          "id": "goodbye",
          "text": "goodbye"
        }
      ]
    }
  ]
}

In the logs I see that a request for a patch occurs but is not applied. Testing in DivKit Playground demo android

Hello! You need a templates field in the patch, even if it is empty

[hulygun]

That?

{
  "patch": {
       "changes": [...],
       "mode": "partial"
  },
  "templates": {}
}

In this form, throws out of the screen. Please get correct structure.

Please make sure that all json in the changes property uses only templates from the patch and not from the main card
