[node]: Cannot call write after stream was destroyed

[ChristineWanjau]

Trying to run @github/copilot-sdk in my ADO task. I am getting this error. The Copilot CLI session never starts. Been running the Copilot CLI commands directly and it seems to work.

I am using @github/copilot-sdk version : "0.1.15, since my task only supports node v20 at the moment.
Any ideas on how I can get the sdk to run in my pipeline.

Thanks for opening this issue, @ChristineWanjau! 👋

I've labeled this as a bug affecting the Node.js SDK and marked it as needs-info since we'll need a bit more detail to help diagnose the issue.

The error suggests the CLI process's stdin stream is being destroyed before the SDK can write to it. To help investigate:

1. Can you share a minimal code snippet showing how you're initializing and using the SDK in your ADO task?
2. Are there any additional logs before this error (especially around CLI startup)?
3. Does the Copilot CLI binary exist and have execute permissions in your ADO pipeline environment?

Since you mentioned the CLI commands work directly, this may be related to how the SDK spawns the CLI process in the ADO environment.

Didn't have copilot CLI installed
