Exception using LUIS dialog

votes

I am using bot framework SDK (3.8.2 / 3.8.3) and getting the following error while using the LUIS dialog with the Bot Framework Emulator.

Any idea?

Exception:

;HelpWhoIsWhoDetailsFromName [File of type 'text/plain']

(strangely whatever my intent is, the exception has a ';' in front )

Did you add all the details of the Exception? What is the Exception type? Because HelpWhoIsWhoDetailsFromName [File of type 'text/plain'] is not really clear – Nicolas R
Can you try commenting the other two intents and see if the exception is being thrown? – Ezequiel Jadib
Yes, tried running the code with only None intent. Strangely , what ever my first LuisIntent name is , the error is that first intent name, prefixed with a ; – punjabi
@Nicolas, the complete error is in the original post itself – punjabi
You don't have more details on this Exception (I saw the stack trace)? Any InnerException or other things during your catch? – Nicolas R

Your problem is you are using "LuisRequest" instead of "LuisResult" in your parameters for each asynchronous method. Only LuisResult works to the best of my knowledge. Change your code to this:

[Serializable]
[LuisModel("XXXXXXX-0ab19c3225cb", "XXXXXXXX582c599915aea4")] // changed the keys 
public class MatLuisDialog: LuisDialog<string>
{

    [LuisIntent("HelpWhoIsWhoDetailsFromName")]
    public async Task HelpWhoIsWhoDetailsFromName(IDialogContext context, LuisResult result)
    {
        await context.PostAsync("From");
        context.Wait(MessageReceived);
    }

    [LuisIntent("")]
    [LuisIntent("None")]
    public async Task None(IDialogContext context, LuisResult result)
    {
    await context.PostAsync("No intent Found");
    context.Wait(MessageReceived);
    }

    [LuisIntent("Help.Greetings")]
    public async Task Greetings(IDialogContext context, LuisResult result)
    {
        await context.PostAsync("Hi, Please enter your matone id, so that i can help you better.");
        context.Wait(MessageReceived);
    }

}
