textprompt after button click in adaptive card doesnt invoke next step

问题

Functionality:

Fetch and display relevant answer from QnAMaker
This response must be followed by an adaptive card with checkboxes
Based on the values selected, invoke a web service to provide the user with required file links.
Display a feedback message 'Did this help?'
Direct the conversation flow based on user response.

Problem Statement: For the step 2 mentioned above, the button click is being handled at the bot.cs file and redirected to a new Dialog. Everything works fine until displaying the feedback message(which is again invoked from a new Dialog). However, after this text prompt the next step is not called and exits with an error: The given key 'dialogs' was not present in the dictionary.

Why does it show that error without going to the next step?

bot.cs

public async Task OnTurnAsync(ITurnContext turnContext, CancellationToken cancellationToken = default(CancellationToken))
{
    if (turnContext.Activity.Type == ActivityTypes.Message)
    {
        if (turnContext.Activity.Text != null)
        {
            if (!dc.Context.Responded)
            {
                // examine results from active dialog
                switch (dialogResult.Status)
                {
                    case DialogTurnStatus.Empty:
                        switch (topIntent)
                        {
                            case ...
                        }

                        break;

                    case ...
                }
            }
        }
        else if (string.IsNullOrEmpty(turnContext.Activity.Text))
        {
            await HandleSubmitActionAsync(turnContext, userProfile);
        }

    {
        userProfile.credentialsCard = true;

    else if(userProfile.credentialsCard == true)

        AddDialog(new TextPrompt("userFeed"));
        AddDialog(new WaterfallDialog(HBFeedbackDialog, waterfallSteps));
        InitialDialogId = HBFeedbackDialog;
    }

    public async Task<DialogTurnResult> CredsValidate(WaterfallStepContext stepContext, CancellationToken cancellationToken)
    {

        ....

        //Invoke Web Service
        var qnaReuslt = await MakeBatchRequestCreds(stepContext.Context, finalSearchList.ToArray());

        return await stepContext.PromptAsync("userFeed", new PromptOptions
        {
            Prompt = stepContext.Context.Activity.CreateReply("Did this help?")
        });
    }
}
