{desc}

Error message

{desc}

What it means

Generic sentinel in login_github_copilot's device-flow poll loop: GitHub returned an error string that is not authorization_pending, slow_down, expired_token, or access_denied. The raw provider error description ({desc}) is embedded; typically an invalid_client, device flow disabled, or unexpected server-side rejection.

Solutions

1. Read the embedded desc for the GitHub OAuth error code
2. Verify the Copilot OAuth client ID/scopes are valid for your account
3. Retry the login; if it persists, check GitHub status or Copilot subscription entitlement
