Subject: Cursor AI Auto-Completion (Cursor Tab) Not Working - "No full commit provider registered" Error in Console

Bug Reports
1

Environment:

  • Cursor Version: 0.49.6 (from logs)

  • Operating System: Windows (Please specify your version, e.g., Windows 10, Windows 11)

  • Primary Context: GDScript development (using geequlim.godot-tools extension, but issue persists without it)

Problem Description:

The AI auto-completion feature (Cursor Tab) is not working. When typing code, no grey-text suggestions appear. However, other AI features like Chat (trae?) and Edit/Generate (augment?) are functioning correctly, indicating that the core AI connection and account authentication seem to be working.

Troubleshooting Steps Performed:

I have performed the following steps extensively to resolve the issue, without success:

  1. Restarted: Restarted Cursor and the computer multiple times.

  2. Reinstalled: Performed a clean reinstall of Cursor, likely including deleting user configuration folders.

  3. Network Issues: Resolved initial network proxy errors (net::ERR_PROXY_CONNECTION_FAILED was present in earlier logs). This was fixed by disabling VPN and checking/correcting system proxy settings. Current logs confirm successful network connections (e.g., update checks run without error).

  4. Cursor Tab Status: Confirmed via the status bar menu that “Cursor Tab” is enabled and shows “✓ Connected”. The options “Disable globally” and “Disable for [language]” are unchecked . (Screenshot available)

  5. Core VS Code Setting: Confirmed “editor.inlineSuggest.enabled”: true is explicitly set in the user settings.json file. (Screenshot available)

  6. Disabled Extensions: Used the “Disable All Installed Extensions” command. The auto-completion issue persisted even with all extensions disabled.

  7. Disabled Language Extension: Specifically disabled the geequlim.godot-tools extension (the primary GDScript support). The issue persisted , indicating it’s not directly caused by this extension.

  8. Checked Settings Files: Reviewed both user and workspace settings.json files; no other settings were found that appear to disable completion features.

  9. Re-authenticated: Logged out and logged back into the Cursor account.

  10. Checked Developer Tools: Monitored the Developer Tools Console during code input.

Key Findings & Errors (from Developer Tools Console):

The Developer Tools Console shows the following potentially relevant messages:

  • Warning: Overwriting grammar scope name to file mapping for scope source.gdscript. (Mentions geequlim.godot-tools and nthn.gdscript-vsc. Note: The nthn.gdscript-vsc extension is not installed on my system.)

  • ERROR: Error checking if repo is ready for background composer: Error: No full commit provider registered (This error originates from workbench.desktop.main.js and seems like a core editor state issue.)

  • Error: Uncaught ResizeObserver loop completed with undelivered notifications. (Likely less relevant UI error.)

(Screenshot of the Developer Tools Console showing these errors is available).

Request:

Given that basic troubleshooting, network issues, extension conflicts, and configuration settings have been ruled out, and considering the core error message (No full commit provider registered) present in the Developer Tools Console, I suspect this might be a bug within Cursor itself or a deeper conflict.

Could you please provide assistance in diagnosing why the Cursor Tab auto-completion feature is not working?

Before sending:

  • Replace “[Specify your version, e.g., Windows 10, Windows 11]” with your actual Windows version.

  • Be prepared to provide the screenshots you took (status bar menu, settings.json, Developer Tools Console) when asked by the support team.

  • Use this text when creating a post on their Discord server (in the appropriate #support or #bug-reports channel) or when creating a new Issue on their GitHub repository.
