Overleaf Workshop compile hangs in VS Code with no visible error while the same project compiles on Overleaf web.

[willytrek]

Describe the bug

When I open the same Overleaf project in VS Code through Overleaf Workshop and try to compile it, the build gets stuck in a loading state and eventually fails, but no clear error message is shown.

I confirmed the following:

• The same .tex file compiles successfully on the Overleaf website
• There are no visible errors in the VS Code Problems panel
• There is no Overleaf Workshop output channel shown in the Output panel
• Reinstalling the extension and reconnecting to Overleaf did not solve the problem

I also checked the local VS Code/extension state:

• There is no obvious http.proxy setting in VS Code user settings
• Overleaf Workshop appears to have valid login information and a project list saved in its state
• I did not find any clear persistent Invisible Mode or websocket disconnect flag
• However, the compile process still hangs, which suggests a connection or initialization issue inside the extension

Expected behavior

Clicking compile should trigger a successful build, or at least show a clear error message if something goes wrong.

How To Reproduce

1. Install and enable Overleaf Workshop in VS Code
2. Open a logged-in Overleaf project
3. Open Optica-template.tex from the project
4. Trigger compile using the extension or its shortcut
5. Observe that the compile stays in a loading state and eventually fails without a clear error

Environment

• Overleaf Workshop Extension version: 0.15.8
• VS Code version: [please fill in]
• Overleaf Edition: Official

Optional Developer Logs

I did not see any useful messages in the Problems panel, and no Overleaf Workshop output channel appeared in the Output panel.

Relevant observations:

• Compilation hangs instead of returning a visible error
• The same project compiles successfully on the Overleaf website, so the project itself seems fine
• The extension appears to have valid login/session data, but the compile flow seems to fail during connection or initialization

If needed, I can also provide Developer Tools Console logs from VS Code.

The root cause is that they hate us.

Fixed by copilot + deepseek v4 pro (w/ max effect), have not checked the compatibility, may only work for the Overleaf website.
