Research direction

Start by following the listed reproduction steps for code-server 4.103.0+ with Copilot Chat 0.29.1 or newer, then review the 28-comment thread for any narrowed cause. No file, test, or entry point is named, logs are empty, and the issue does not establish whether the outcome should be a fix or documentation.

Description

bug triage

Edit by @code-asher:

There have been a few reported issues: either Copilot does not install, installs but does not run, runs but signing in does not work, or runs but not correctly.

Not sure what we can do, it is not something we can debug because running Copilot in code-server is a violation of the license (as far as we understand) and it is closed source.

Maybe we will need to add documentation that Copilot does not work, or maybe there are other similar extensions we can test that will reveal what the underlying issues are, assuming they are code-server issues and not something in the extension.

Is there an existing issue for this?

Steps to Reproduce

Run code-server 0.103.0+.
Install Copilot Chat extension (0.30+ can be installed from Marketplace, but not on 4.102.3 — only via VSIX).
Try to use Copilot Chat (tested with 0.29.1 and 0.30+).

Expected

Copilot Chat should either:
Continue working on 4.103.0+ as it did before, or
Fail with a clear error instead of hanging.

Actual

On 4.103.0+, Copilot Chat 0.29.1 no longer works:
No requests go through.
Output panel does not show fetched model metadata.
Copilot Chat displays "Working..." indefinitely.
