Trouble Debugging AI Agent Bot in Teams Using Teams Toolkit in VS Code

I am trying to build an AI agent bot in Teams using the Teams Toolkit in the VS Code plugin, following the instructions in this LINK.

I was able to successfully complete it until step G, where I updated the Azure OpenAI key, endpoint and deployment name. 

However, when I try to debug in the Test Tool, it does not open the bot, and it doesn't get connected. I get the following error:

Please help me unblock myself.  I also need help on how to finally test this in teams or a web app. Currently in the custom bot I created (in python), the config.py file requires bot ID and password (where do I get those?) but the link only instructs updating the Azure openAI credentials in .env.testtool.user. What am I missing?
