Am I incorrectly using PromptOptions?

Question

I'm trying to create a ChoicePrompt for my chatbot, but for some reason I can't import the PromptOptions interface. When I try including it in the botbuilder-dialogs imports:

const { DialogSet, WaterfallDialog, ChoicePrompt, WaterfallStepContext, PromptOptions } = require('botbuilder-dialogs');

VS Code doesn't recognize it as being part of the package, and try using it when creating the prompt in the WaterfallStepContext:

async (step = new WaterfallStepContext()) => {
       const semOptions = ["Fall", "Winter", "Summer"];
       options = new PromptOptions({ 
              prompt: `What semester are you currently in, ${this.name}?`, 
              choices: semOptions 
       });
       return await step.prompt("semPrompt", options);
}

I get a unhandled error:

TypeError: PromptOptions is not a constructor

I reinstalled the latest version botbuilder-dialog package several times but to no avail. Can anyone offer any insight as to what I may be doing wrong?

PromptOptions, is an interface with configurable options you pass in the prompt. You don't need to 'construct' it via new PromptOptions.

Wrt you question you could do something like:

Add 'ChoiceFactory' utilities

const { WaterfallDialog, ChoiceFactory, ChoiceFactory, ConfirmPrompt, TextPrompt } = require('botbuilder-dialogs');

In your dialogs constructor you add the prompt and add it to the dialogSet:

 this.addDialog(new ChoicePrompt(CHOICE_PROMPT_NAME));

In your dialogstep you call the prompt and pass the options

    async Step(stepContext) {
        const SEMOPTIONS = ['Fall', 'Winter', 'Summer'];
        return await stepContext.prompt(CHOICE_PROMPT_NAME, {
            prompt: `What semester are you currently in, ${this.name}?`,
            retryPrompt: 'Please select one of the options',
            choices: ChoiceFactory.toChoices(SEMOPTIONS),
            style: 5
        });
    }

Btw: It seems you are using C# / Python classes in your Javascript code. The SDK documentation for JS is located here:
