Copilot Chat does not work with Coder v4.103+

[maxorlovsky]

Is there an existing issue for this?

• I have searched the existing issues

OS/Web Information

• Web Browser: Brave
• Local OS: macOS
• Remote OS: Debian
• Remote Architecture: x86_64
• code-server --version: 1.102.3
  6f3d0a7
  x64

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.

Are you accessing code-server over a secure context?

I think it is an extension issue. Do you see any logs in the browser console? When I installed the extension I got Chat model provider uses UNKNOWN vendor copilot. I think the chat extension might require a second Copilot extension which is not available on Open VSX.

Although, you did say it worked before, which means it might be a different problem, or maybe they split up the extension. Either way it does seem more likely to be an extension issue at first glance.

same error

Just to clarify:
On code-server v4.102.3 both Copilot Chat 0.29.1 and the latest Copilot (1.372.0 via VSIX) work fine.
On code-server v4.103.0+, Copilot Chat 0.29.1 stops working, and 0.30+ can be installed from the Marketplace but also doesn't function as expected, it just hangs on the first request and now even displaying option to chose models in a dropdown.

That’s why I wondered if there might have been a breaking change between VS Code 1.102.x and 1.103.x that affects how the extension integrates, rather than it being purely an extension issue.

I totally understand it may be on the extension side, but since AI agent features are becoming more important, it might be worth checking whether there is something code-server-specific in play here.

[code-asher]

Yeah it could be something in code-server, we do have some patches that could be related. I wish we could reproduce with an extension that was publicly available though, from what I understand the Copilot extension is still not available outside the Microsoft marketplace and installing it into code-server is a breach of the license.

I also see this error; the stack trace indicates it is the chat extension trying to do some auth. Not sure what this module is or why it is missing.

[smerschjohann]

hm seems to be this one: https://www.npmjs.com/package/@azure/msal-node-runtime?activeTab=dependents which comes with msal-node-extensions. It seems that this module just needs to be provided

[smerschjohann]

my guess is we need to search around the changes regarding the microsoft-authentication extension .. it should normally provide the missing modules.

works again with latest version of code-server (v4.104.1), github copilot (1.370.1783) and github copilot chat
(0.31.1). But you have to login on the left side (account bubble down left)
