VSCode GitHub Copilot Edit tool cannot be used to edit file open from Overleaf Workshop

[wongluffy]

Describe the bug

The Overleaf Workshop plugin is installed in VSCode, and it connects to an account on the Overleaf official website via cookies through the Overleaf Workshop plugin. One of the projects is opened, and a tex file is opened within the project.
GitHub Copilot is then launched, and the edit option is selected.
After entering an edit command, GitHub Copilot responds: "It seems the file is not recognized as being inside the current workspace, so I cannot directly edit it. Could you confirm if the file path is correct or provide access to the file within the workspace?"

Expected behavior

Use GitHub Copilot's edit feature to edit files in projects opened by Overleaf Workshop

Environment

• Overleaf Workshop Extension version: [latest]
• VS Code version: [latest]
• Overleaf Edition: Official / Community

My logs show this problem: overleaf-workshop failed to create file system provider. I don't know what the problem is.

As I showed above, the copilot edit is possible. Please let me know the detailed steps to reproduce the error.

I guess you may run "Overleaf Workshop" and "GitHub Copilot" in ssh remote workspace, which may raise this error.

[wongluffy]

I am running "Overleaf Workshop" and "GitHub Copilot" locally. vscode_editFile_internal and copilot_insertEdit cannot handle virtual workspace paths overleaf-workshop:\www.overleaf.com.

It works fine on my colleague's computer.
I uninstalled vscode and cleared all plugins and configurations, reinstalled the latest version of vscode and the "Overleaf Workshop" "GitHub Copilot" plugins, logged into my colleague's account, and synchronized his plugins and configurations, but found that it still doesn't work properly.

It should be related to my computer, but I really can't figure out where the problem is. Has anyone else encountered this situation?

I face connection lost recently, and then cannot proceed

[yizhenwang2002]

I think this is an issue related to empty diagonistic array if context:vscode.CodeActionContext is

{diagnostics: [], triggerKind: 2}

Accessing the first eleemnt in context will always raise undefined in this case. I believe returning an empty array would also help.

The one in latex workshop is

I'm using MacOS, get the same problem. Within overleaf worksapce, the Copilot is not sendable and request. No error, warns occurs, just cannot send the request.

I also get the same problem. Within the Overleaf workspace, the Copilot is not available for sending or requesting.
My logs show this problem:

I'm running into the exact same problem using Gemini Code Assistant. Did anyone seem to solve this?
I feel like this happens because of a virtual path and saving the project locally might help. But as I am working closely with others on the document, I prefer to keep it fully online.

[yblei]

Same problem here, also on macOS. GPT-5 returns:
Progress: I attempted to read root.tex but the Overleaf-backed file isn’t accessible via tools here. If you paste the current subsection text (or grant me the exact heading), I’ll revise it directly and update root.tex for you.

Did anyone find a solution?
This would be a major productivity boost.
