Body

Hello, I am unable to use Copilot Chat on github.com to access any of my repositories (e.g., DuVyn/FitTrack).

Every time I make a request that requires repository access, it immediately fails with the generic error message: "I'm sorry but there was an error. Please try again."

The expected permission prompt to grant access never appears.

We have already tried the following troubleshooting steps without success: 1. Checked "Authorized GitHub Apps": "Copilot Chat App" is authorized, but its configuration page says "Copilot Chat App has not been installed on any accounts you have access to." 2. Checked "Installed GitHub Apps": This section is empty. There is no "Copilot" app installed. 3. Attempted to install the "Copilot" app from the GitHub Marketplace. However, the search results are confusing and do not seem to offer the main application for installation, only extensions and Actions. 4. Attempting to trigger the permission prompt by issuing a direct command in the chat (e.g., "summarize the README") consistently fails with the same generic error.

This issue seems to be a deeper problem with my account's integration with the Copilot application, which cannot be resolved through standard UI settings.

Could you please investigate the backend logs for my account (DuVyn) to resolve this issue?

Yeah, I think I know what’s going on here. Copilot Chat can’t access your repos because, even though the app shows up in your authorized apps, it hasn’t actually been installed on your account. That’s why the permission prompt never appears and every repo-related command fails.

Hi @DuVyn,

Thank you for the detailed description of your issue. Based on what you've shared and common patterns seen with Copilot Chat access problems, here’s a comprehensive approach to resolve this:

Root Cause:
The “Copilot Chat App” appearing under Authorized GitHub Apps but not being installed on any of your accounts indicates that although authorization is granted, the actual GitHub App installation step is missing. Without installation, Copilot Chat cannot prompt for repository access permissions or operate on your repos, resulting in the generic error you see.

Recommended Steps to Resolve:

1. Install the Copilot GitHub App on your account or organization

   • Go to the GitHub Marketplace for Copilot and look for the official "GitHub Copilot" application, not extensions or actions.
   • If you do not find it directly, ask an organization admin (if applicable) to install it on your behalf.
   • The app installation is mandatory for Copilot Chat to function correctly with your repos.

2. Verify App Installation & Permissions

   • After installation, confirm it appears under your “Installed GitHub Apps” and has repository access permissions.
   • You should then see permission prompts from Copilot Chat when accessing repos for the first time.

3. Reauthorize Copilot Chat in your GitHub account settings

   • Navigate to Settings > Applications > Authorized OAuth Apps and revoke Copilot Chat authorization.
   • Then, retry accessing the repo with Copilot Chat to trigger a fresh permission prompt.

4. Clear browser cache / cookies or try a private browsing session

   • Sometimes cached sessions can block permission dialogs.

Additional Notes:

• If you belong to an organization, the app might need to be installed at the org level, and you may need admin assistance.
• If the GitHub Marketplace still doesn’t list the official Copilot app for installation, this may be a temporary availability issue; contacting GitHub Support can help in this case.

If after these steps the issue persists, please provide any error logs or screenshots, and consider opening a support ticket with GitHub for deeper backend investigation.

I hope this helps you regain full functionality of Copilot Chat on your repositories quickly!

Best regards.

Hi! It seems the issue is related to Copilot Chat not being properly installed or authorized for your account. A few points to note:

Copilot Chat App Installation:

Even if the app shows as authorized, it must be installed on your account or organization to access your repositories.

Marketplace Confusion:

The main Copilot Chat app isn’t listed like extensions or Actions. You usually enable it directly via GitHub.com under Settings → Copilot.

Permission Prompt:

If the prompt never appears, it indicates the backend hasn’t linked your account to the Copilot Chat app.

Next Steps:

Contact GitHub Support directly with your account info. They can check backend logs and complete the installation link for your account.
