actions-on-google - 得到 "Sorry, I didn' t 得到任何响应。”当我尝试切换功能时的消息

Question

当我尝试多面对话(从 Google Home 切换到 Android Google Assistant)时，我收到“抱歉，我没有得到任何回应”。
我正在使用 Action SDK，语言环境是“ja”。

这是我的回应:

{
    "conversationToken": "(token)",
    "expectUserResponse": true,
    "isInSandbox": true,
    "expectedInputs": [
        {
            "possibleIntents": [
                {
                    "intent": "actions.intent.NEW_SURFACE",
                    "inputValueData": {
                        "@type": "type.googleapis.com/google.actions.v2.NewSurfaceValueSpec",
                        "context": "Sure, I have some sample images for you.",
                        "notificationTitle": "Sample Images",
                        "capabilities": [
                            "actions.capability.SCREEN_OUTPUT"
                        ]
                    }
                }
            ],
            "inputPrompt": {
                "richInitialPrompt": {
                    "items": {
                        "simpleResponse": {
                            "textToSpeech": "PLACEHOLDER_FOR_NEW_SURFACE"
                        }
                    }
                }
            }
        }
    ]
}

有谁知道为什么？

事实证明，这不是某个语言环境中的错误，但是 askForNewSurface 目前仅支持英语语言环境。
这是我从 AoG 支持中得到的:

Hi Jan,

Thank you for your interest in Actions on Google. askForNewSurface is indeed only available for English locales. We are in the process of changing the documentation to reflect those restrictions. Sorry for the confusion. We do not have any set det for the release of this feature in other locales.

Kind Regards,

Jean-Charles, Actions on Google Support Team.
