Authentication troubleshooting
If the above steps do not solve your issue, the problem may be related to the recent changes in authentication, specifically the token system. To resolve the issue:
- Remove the existing personal access token from your GitLab account settings.
- Reauthorize your GitLab account in VS Code using OAuth.
- Test the Code Suggestions feature with different file extensions to verify if the issue is resolved.
