Get value of choiceSet within adaptive card in Dialog - node.js

Question

I have a step in my dialog where I send an Adaptive Card with a choice set. When the user selects a choice on the card and presses submit, how would I capture that value and continue with my dialog?
If there isn't an official way to do this, any suggestions about some hacks would be nice. Thanks ahead of time!
Here is my dialog class:
import { AdaptiveCards } from "#microsoft/adaptivecards-tools";
import {
ActivityPrompt,
ChoicePrompt,
ComponentDialog,
Dialog,
DialogSet,
DialogTurnStatus,
TextPrompt,
WaterfallDialog,
WaterfallStepContext,
} from "botbuilder-dialogs";
import { TicketProfile } from "../TicketProfile";
import rawCategoryListCard from "../adaptiveCards/categoryList.json";
import { ActivityTypes, CardFactory, MessageFactory } from "botbuilder";
const CHOICE_PROMPT = "CHOICE_PROMPT";
const HELP_PROMPT = "HELP_PROMPT";
const SUBJECT_PROMPT = "SUBJECT_PROMPT";
const CATEGORY_PROMPT = "CATEGORY_PROMPT";
const AREA_PATH_PROMPT = "AREA_PATH_PROMPT";
const REPORTED_PROBLEM_PROMPT = "REPORTED_PROBLEM_PROMPT";
const WATERFALL_DIALOG = "WATERFALL_DIALOG";
const CONFIRM_PROMPT = "CONFIRM_PROMPT";
export class TicketingPreferences extends ComponentDialog {
ticketProfile: any;
constructor(userState?: any) {
super("TicketingPreferences");
this.ticketProfile = userState.createProperty("TicketProfile");
this.addDialog(new ChoicePrompt(CHOICE_PROMPT));
this.addDialog(new TextPrompt(SUBJECT_PROMPT));
this.addDialog(new ActivityPrompt(CATEGORY_PROMPT, this.inputValidator));
this.addDialog(new TextPrompt(AREA_PATH_PROMPT));
this.addDialog(new TextPrompt(REPORTED_PROBLEM_PROMPT));
this.addDialog(
new WaterfallDialog(WATERFALL_DIALOG, [
this.choiceStep.bind(this),
this.subjectStep.bind(this),
this.categoryStep.bind(this),
this.areaPathStep.bind(this),
this.reportedProblemStep.bind(this),
this.summaryStep.bind(this),
])
);
this.initialDialogId = WATERFALL_DIALOG;
}
async run(turnContext, accessor) {
const dialogSet = new DialogSet(accessor);
dialogSet.add(this);
const dialogContext = await dialogSet.createContext(turnContext);
const results = await dialogContext.continueDialog();
if (results.status === DialogTurnStatus.empty) {
await dialogContext.beginDialog(this.id);
}
}
async choiceStep(stepContext: WaterfallStepContext) {
return await stepContext.prompt(CHOICE_PROMPT, {
prompt: "How can I help you?",
choices: ["Create Ticket", "Update Ticket", "Delete Ticket"],
});
}
async subjectStep(stepContext: any) {
stepContext.values.choice = stepContext.result.value;
return await stepContext.prompt(
SUBJECT_PROMPT,
"What is the ticket title?"
);
}
async categoryStep(stepContext: any) {
stepContext.values.subject = stepContext.result;
const exampleCatgory = {
category: [
{
title: "Category 1",
},
{
title: "Category 2",
},
{
title: "Category 3",
},
],
};
const card =
AdaptiveCards.declare(rawCategoryListCard).render(exampleCatgory);
const form = MessageFactory.attachment(CardFactory.adaptiveCard(card));
return await stepContext.prompt(CATEGORY_PROMPT, { prompt: form });
}
async areaPathStep(stepContext: any) {
if (stepContext.result) {
stepContext.values.category = stepContext.result;
return await stepContext.prompt(
AREA_PATH_PROMPT,
"What is the area path of your ticket?"
);
}
}
async inputValidator(promptContext) {
const userInputObject = promptContext.recognized.value.value;
return true;
}
}
