`GitHub Copilot SDK` sample local invoke fails on Windows: session.create requires /home, resulting in unexpected EOF

[Menghua1]

Description:
When testing Scenario 2: GitHub Copilot SDK sample (Invocations), after azd ai agent run successfully started locally, executing the local invocation command azd ai agent invoke --local --protocol invocations '{"input": "What can you help me with?"}' failed. The local log showed the error: "Directory does not exist or cannot be accessed: /home". See the image below for details.

Steps to Reproduce:

1. mkdir github-copilot-invocations and cd github-copilot-invocations
2. Run azd ai agent init --manifest "https://github.com/microsoft-foundry/foundry-samples/blob/main/samples/python/hosted-agents/bring-your-own/invocations/github-copilot/agent.manifest.yaml" and select location northcentralus.
3. Run azd up.
4. Run azd env set GITHUB_TOKEN "<github token>".
5. Run azd ai agent run.
6. From a second terminal, run azd ai agent invoke --local --protocol invocations '{"input": "What can you help me with?"}'.
   Environment:

• Azd version: azd version 1.24.2-daily.6223381 (commit 7d52038731150e12a5f12aadbfcb09d7413ed0f5) (daily).
• AI Agent Extension version: 0.1.28-preview
• Manifest URL: https://github.com/microsoft-foundry/foundry-samples/blob/main/samples/python/hosted-agents/bring-your-own/invocations/github-copilot/agent.manifest.yaml
• OS: Windows
• Location: northcentralus.

Expected Behavior:
Local invoke can succeed.

@Menghua1 does it work in a Linux environment? I couldn't repro this inside a Linux Dev Container, so this might be Windows specific.

@JeffreyCA I've verified this on both Linux and macOS, the local invoke succeeds.

However, remote invoke fails in both Linux and macOS, reporting session_not_ready errors, as shown in the image below:

Environment:

• Azd version: azd version 1.25.0-beta.1-daily.6251773 (commit 6293e579450bb8c3ea06c5ceede0c69b8f21fec7).
• AI Agent Extension version: 0.1.29-preview
• Manifest URL: https://github.com/microsoft-foundry/foundry-samples/blob/main/samples/python/hosted-agents/bring-your-own/invocations/github-copilot/agent.manifest.yaml
• OS: Linux and Mac
• Location: northcentralus.

@JeffreyCA and @rajeshkamal5050 Based on testing with the latest azure.ai.agents 0.1.31-preview, this issue can still be reproduced.

Current results:

• On Windows, the local invoke failure is still reproducible.

• On Linux, the remote invoke failure is also still reproducible.

Environment:

• Azd version: azd version 1.25.0-beta.1-daily.6272386 (commit 832a81c928f5f48b268a31600e1182e172320e72) (daily).
