Agent SDK with Python sample code

[dwksydon]

Hi team,
I have a Copilot Studio Agent.
I tried to connect the sample code with my agent.
However, I only received "None" from the terminal. (VS Code)
This is what I tested with my agent in Copilot Studio.

After I configured the .env following with the guide in readme.md, I encountered "None".

I looked at the code but there is nothing I need to do but copy env.template to .env update it with the correct value.
Any suggestions?

This is my folder structure in VS Code

Hello @dwksydon have you done the setup described in this readme? THe instructions are for the C# version but setup in mcs and the entra app should be the same.

On our side local testing of this sample seems to be working

Hi @axelsrz,
I did.
Since I posted my question here, I tried a few things including the sample code with c# as well.
When I tested with this code(Python example) and c# against my Copilot Studio agent, both samples failed.
When I retried the c# sample with a very simple agent without tools or knowledge, it worked.
I believe this sample code must work with this dummy agent.
However, I still don't understand the root cause. Roughly guessing, the "computer use" tool might be the root cause, but the sample didn't try to execute this tool.
If you have a list of limitation, please share the details.
