dialogbot | provide search-based dialogue | Natural Language Processing library

For a multi language bot running on Messenger I need to store the current language of the user in botState. This works fine for most components:

In Index.js the userState instance is created and passed to the main dialog

We have been using the bot framework for a while now and are very happy with it. We use the stepContext.Parent.CancelAllDialogsAsync() method. This works fine but we want to pass a result or trigger some kind of action in the bot code. We would like to pass a value.

I noticed the optional eventName and eventValue parameters, but I cannot find any way to use them. I found this documentation for the method but the eventName and eventValue are not explained at all. https://docs.microsoft.com/en-us/dotnet/api/microsoft.bot.builder.dialogs.dialogcontext.cancelalldialogsasync?view=botbuilder-dotnet-stable.

I thought that it would trigger the DialogBot's OnEventActivityAsync method, but it doesn't.

Our use case is as follows: At some point in the conversation our bot asks the user a question. When the user doesn't answer the question multiple times, but instead keeps asking their own question we call CancelAllDialogsAsync. The bot will get back to the MainDialog and wait for user input, so the user will have to ask their question again. We don't want the user to have to ask agian, so we want to cancel all dialogs and go back to the MainDialog passing the users question so the MainDialog can pick a way to answer it.

Any help is appreciated.

My bot processes incoming user messages and takes action based on the intent. For simple, one shot answers that do not require multiple passes between users and the bot, it works well. Now when I want to implement a dialog, it's getting tough. Once the user sends the message and the Dialog gets triggered, the bot asks the user for input. Once the user provides the input, this input is being again processed by LUIS to understand the intent. However, I do not want this to happen as this abandons the ongoing Dialog.

I want to understand if there some way I can detect if a Dialog is under progress and what dialog is it. If I can know this, I can skip the LUIS intent check part and direct the logic to Dialog. I've used the Multi-turn Prompt as a basis for this. Below is what I expect.

My bot right now is using local memory, the goal is whenever a conversation end. I want to delete everything from local memory about this user. So I tried this onEndOfConversation.

Apparently this error shows up saying that onEndOfConversation is not a function.

This is my code :

I have a simple bot that listens for a facebook event trigger (not a message) When it gets the trigger, it should start a new Dialog (RegisterPledgeDialog) and push it to the stack. But I don't know how?

I am having a problem with the bot state. I am pretty much following the way they said to save user state here. My only changes is that I am using the dialog bot that is in Visual Studio. When I do the last step in my main dialog I set several properties to values in my user profile object and then I call SaveChangesAsync and then heads back up to handle the next request. When I get the next request. I do the userStateAccessors.GetAsync call to get the latest version just to keep it fresh. But I noticed that my changes were not saved.

Has anyone else had this problem. My employer wants the chatbot to retain state per user so that they wont have to enter in all the information per request.

I am using .Net Core 2.1 to build a Bot with version 4 like the example here and I am not getting any response from the Bot Framework Emulator or code error from Visual Studio. When I go from url it says this error on image below. I think is something wrong with the dependency injection. What I am doing wrong?

On startup:

I am trying to send a greeting message at the moment the web is loaded and the chatbot is initialized. It works with the emulator but it doesn't seem to work that straight forward with on the webchat channel.

I have researched and found a couple of useful links but I am missing something...

So far this is my code:

This issue is linked to my previous post related to an issue with MS Bot framework oAuth Authentication in MS Teams Chanel. The OAuth Authentication has started working but, am facing this issue as a result of the suggested code changes to enable OAuth Authentication.

Linked Post URL: Sign-in button prompts for Credentials and successfully authenticates but, doesn't log-in the user

Used the following Git Hub Code Sample as a basis for the OAuth code and retrofitted to my existing ChatBot: https://github.com/microsoft/BotBuilder-Samples/tree/master/samples/csharp_dotnetcore/46.teams-auth

• The Class hierarchy mention in the question is similar to the above code sample.

The MainDialog class in my case uses both LUIS and Adaptive cards to drive the conversational flow.

Due to the following change in the DialogBot class, the "options" paramater in MainDialog .BeginDialogAsync overridden method now gets NULL value instead of a proper value it used to previously get before the change.

As the MainDialog .BeginDialogAsync overridden method has all the code to detect returned value by the Adaptive Card in the "options" paramater, now that, it is being returned as null, the adaptive cards don't work.

However, the LUIS conversational logic works after successful OAuth Authentication from within MS Teams.

MainDialog.BeginDialogAsync(DialogContext outerDc, object options = null, CancellationToken cancellationToken = default(CancellationToken)){....}

As per the sample oAuth Sample code provided at https://github.com/microsoft/BotBuilder-Samples/tree/master/samples/csharp_dotnetcore/46.teams-auth

1. I inherited DialogBot from TeamsActivityHandler.

2. Implemented the suggested code in the method TeamsBot.OnTeamsSigninVerifyStateAsync(ITurnContext turnContext, CancellationToken cancellationToken)

3. Inside the overridden method DialogBot.OnMessageActivityAsync(ITurnContext turnContext, CancellationToken cancellationToken), I replaced "a" with "b"

   a. await _dialog.Run(turnContext, _botStateService.DialogStateAccessor, cancellationToken);

   b. await _dialog.RunAsync(turnContext, ConversationState.CreateProperty(nameof(DialogState)), cancellationToken);

The simple change of .Run(....) to .RunAsync(....) probably misses the value and makes the Adaptive Card code non-functionl due to the mission "Options" parameter value in MainDialog.BeginDialogAsync(..) method

In the DialogBot.OnMessageActivityAsync(...) , when I replace b with c then, the "options" parameter in MainDialog .BeginDialogAsync(...) starts getting the requisite value to make the Adaptive card code work but, only if the user is already OAuth Authenticated i.e. when clicking sign-in button is not required.(But brings up another issue mentioned in "When It Doesn't Work section")

b. await _dialog.RunAsync(turnContext, ConversationState.CreateProperty(nameof(DialogState)), cancellationToken);

c. await _dialog.Run(turnContext, ConversationState.CreateProperty(nameof(DialogState)), cancellationToken);

After making the change mentioned in the "When It Works" section if, the user types any utterance like "Hi", it causes an exception in the DialogBot.OnTurnAsync(....) method. This error then keeps coming every time and am not able to proceed with the Bot conversation.

• Exception when the user types any utterance i.e. when the user hasn't yet signed it

• Bot Emulator screenshot when the above exception comes up

In this scenario of OAuth Authentication in MS Teams, It's definite that I am messing up in state management in coordination with how Adaptive Card Submit click should be handled i.e. to retrieve user-provided values.

Would need inputs to handle this scenario where MS Teams OAuth Authentication is involved with a chatbot catering to both LUIS NLP based conversation and Adaptive Cards based dialog flow

• The Adaptive Cards and LUIS based dialog flow was perfectly working until the Above changes for fixing OAuth Authentication in MS Teams were done.
• Am using my Phone HotSpot for internet with no Proxy in between.
