node.js - Card显示后，如何在sdk v4.4中继续 waterfall 式对话框流程

Question

我引用了示例代码并尝试了简单的场景来显示卡片。卡片显示后如何继续Waterfall_Dialog？

我指的是示例代码 05.multi-turn-prompt 和 06.using-cards - ( https://github.com/microsoft/BotBuilder-Samples/blob/master/samples/javascript_nodejs/05.multi-turn-prompt/dialogs/userProfileDialog.js )

      ...this.addDialog(new WaterfallDialog(WATERFALL_DIALOG, [
        this.initialData.bind(this), 
        this.displayCard.bind(this),    
        this.text.bind(this)
    ])); ...

async run(turnContext, accessor) {
   ...}

async initialData(step) {
    return await step.prompt(NAME_PROMPT, `Type anything to display card`);
} 

async displayCard(step) {
   await step.context.sendActivity({ attachments: [this.createAdaptiveCard()]});                
}

async text(step) {
    console.log("step.res"+step.context.activity.text);
    await step.context.sendActivity("Thank you for selecting an option");

}

<小时/>

async displayCard(step) {
   await step.context.sendActivity({ attachments: [this.createAdaptiveCard()]});                
  return await this.text(step);
} 

显示卡片并继续 waterfall 对话框。

显示卡片后，它应该继续流程并显示“感谢您选择一个选项”，

1. 但是它将进入 Begin_Dialog 并要求“键入任何内容以显示卡片”

2. 如果我通过调用下一个对话框来尝试其他方法。我得到“哎呀。出了点问题!”“[onTurnError]:TypeError:无法读取未定义的属性“状态””

要前进到下一个对话框步骤，您需要在包含该卡的步骤之后调用 NextAsync。

例如，

private async Task<DialogTurnResult> StartSelectionStepAsync(WaterfallStepContext stepContext, CancellationToken cancellationToken)
{
    // Set the user's age to what they entered in response to the age prompt.
    var userProfile = (UserProfile)stepContext.Values[UserInfo];
    userProfile.Age = (int)stepContext.Result;

    if (userProfile.Age < 25)
    {
        // If they are too young, skip the review selection dialog, and pass an empty list to the next step.
        await stepContext.Context.SendActivityAsync(
            MessageFactory.Text("You must be 25 or older to participate."),
            cancellationToken);
        return await stepContext.NextAsync(new List<string>(), cancellationToken);
    }
    else
    {
        // Otherwise, start the review selection dialog.
        return await stepContext.BeginDialogAsync(nameof(ReviewSelectionDialog), null, cancellationToken);
    }
}

在上面的代码片段中，如果用户的年龄不正确，则会显示一条消息说明同样的情况。调用 return wait stepContext.NextAsync() ，使对话框前进到下一步。如果用户已成年，则开始新的对话框(“ReviewSelectionDialog”)。该代码片段来自“使用分支和循环创建高级对话流”的文档，位于 here ，你可以引用一下。
