[Slack] Skill not answering messages to Virtual Assistant/Root Bot connected to Slack

Version

Describe the bug

I have a Virtual Assistant created from VSIX, a Skill created from VSIX (C# both) and they are connected. When I test this locally, it works just perfectly, but when I follow the Slack Adapter Sample and implement the SlackAdapter and SlackController in the Virtual Assistant, the Skill messages never show up in Slack. I tried debugging both locally, using Ngrok, and I can see how the Skill is responding to api/skill endpoint with a 500 Internal Server Error.

To Reproduce

Steps to reproduce the behavior:

1. Create Virtual Assistant with VSIX
2. Create Skill with VSIX
3. Deploy Virtual Assistant with the deploy.ps1 script located in ./Deployment/Scripts/
4. Deploy Skill with the deploy.ps1 script located in ./Deployment/Scripts/
5. Connect Skill with Virtual Assistant using Botskills
6. Implement SlackAdapter and SlackController
7. Create Slack App and configure Virtual Assistant with Slack configuration
8. Publish changes in the Virtual Assistant
9. Test in Slack

Expected behavior

Just like in the Emulator, I would expect to receive the Skill messages.

Hi @Batta32, thanks for the quick answer! I tried myself the sample 80.skills-simple-bot-to-bot and found that it also has the same problem when using Slack and communicating with a Skill. As you can see in this screenshot, Ngrok is receiving the 500 Internal Server Error response:

I followed the Sample 80’s instructions, created 2 App Registrations for each Bot, I run Ngrok in port 3978 and configured a Slack app with that URL. When I invoked the Skill in Slack, I had no answer.

Previously I had tested in the Emulator and everything worked just fine.

The only changes I made to the Bots are:

1. Add the Slack settings in appsettings.json file
2. Copy the SlackController and SlackAdapter from sample 60.slack-adapter
3. Inject the SlackAdapter in the Startup just like in the 60.slack-adapter

Some screenshots of the changes applied:

If you need anything else just let me know. Thanks for your time! 😊
