Operation returned an invalid status code 'Forbidden`. Botframework v4

Question

So i created a bot in azure and downloaded it. The free 1000 calls from LUIS reached its limit. I created a subscription in azure portal (I did do the docker container something). Followed this guide until step 6. When i click the endpoint url and query directly in the browser it is working fine.

I added it to the bot via Bot Emulator by clicking + sign in services and adding the bot model there. But when i run bot i get the title error. I noticed in the .bot file the authoring key and subscription key added by the bot emulator is the same.

So i changed the subscription key to the one of the keys generated by azure and still the same error. I have tried reseting the authoring key still same and deleting my luis.ai account and created a new one. (still same email because that is the one logged in azure portal.) and still the same.

Here are some pictures for reference and the error.

I also tried testing it in luis.ai and got this result.

but when i check it is set to the new resource.

Here is a pic of the bot file after adding luis via Bot emulator. It has same authoring key and subscription key (still forbidden)

so i changed it now with subscription key (still forbidden).

Here it is working properly when tested directly in the URL.

For reference:

azure portal

luis.ai

and the error

How i add luis in the bot.

Here is the code for the bot service.

using System;
using System.Collections.Generic;
using Microsoft.Bot.Builder.AI.Luis;
using Microsoft.Bot.Configuration;

namespace Microsoft.BotBuilderSamples
{
    public class BotServices
    {
        public BotServices(BotConfiguration botConfiguration)
        {
            foreach (var service in botConfiguration.Services)
            {
                switch (service.Type)
                {
                    case ServiceTypes.Luis:
                        {
                            var luis = (LuisService)service;
                            if (luis == null)
                            {
                                throw new InvalidOperationException("The LUIS service is not configured correctly in your '.bot' file.");
                            }

                            var endpoint = (luis.Region?.StartsWith("https://") ?? false) ? luis.Region : luis.GetEndpoint();
                            var app = new LuisApplication(luis.AppId, luis.AuthoringKey, endpoint);
                            var recognizer = new LuisRecognizer(app);
                            this.LuisServices.Add(luis.Name, recognizer);
                            break;
                        }
                }
            }
        }

        public Dictionary<string, LuisRecognizer> LuisServices { get; } = new Dictionary<string, LuisRecognizer>();
    }
}

I am trying to solve this for 4 days already. Thanks!

Could you share the code where you initialize the LuisApplication? You can find an example here. — Mick
Thank you for your response. I updated the question with the botservice of luis application. — user10860402
Can you verify something? Remove those luis entries from your bot file. Add a new one, ensuring that you use the endpoint keys beginning with 12ccc or b575. Do not use the authoring key beginning with ad9c at all. Do you still get the 403 error? — mdrichardson
@mdrichardson The emulator add those keys automatically. Then i changed them directly in the bot file, is it okay? And yes sir i am still getting the forbidden error when i changed the subscription keys to one of the keys. Is it relevant that i have not published this bot yet in azure? Because this is new i refactored the codes. But this' bots previous version is published in azure. — user10860402
I think its also worth mentioning that i created a new luis.ai account with free starter key and no subscription key and it worked with no problem. — user10860402

Thank you for all of the images. That is a HUGE help! Here's the problem:

By default, your code looks for the AuthoringKey in this section (second line):

var endpoint = (luis.Region?.StartsWith("https://") ?? false) ? luis.Region : luis.GetEndpoint();
var app = new LuisApplication(luis.AppId, luis.AuthoringKey, endpoint);
var recognizer = new LuisRecognizer(app);
this.LuisServices.Add(luis.Name, recognizer);

Since your .bot file still has the authoringKey set to the one that starts with ad9c..., which has hit its limit, your bot keeps running into the 403 error.

So, in your .bot file, replace that authoringKey with one of your endpointKeys (they start with 12ccc... or b575...).

I understand your confusion with this, especially since this requires you putting an endpointKey in your authoringKey property. I know there's some changes on the horizon to how LUIS bots will use keys, but those are probably a month or more out.

Alternatively, you can change:

var app = new LuisApplication(luis.AppId, luis.AuthoringKey, endpoint);

to:

var app = new LuisApplication(luis.AppId, luis.SubscriptionKey, endpoint);

Note: If you make either of these changes, LUIS can only query (which is usually fine), since Authoring Keys do everything else (see reference, below)
