GitHub Copilot CLI bug: Mission Control dashboard links 404 as sessions live under /agents/tasks path
dai · ghdev · 2026-09-09
A bug filed in github/copilot-cli (#4775) reports that the Mission Control "Created by me" dashboard on github.com renders remote session links pointing to a non-existent path, returning 404 even though the sessions are alive and reachable via copilot --resume=<uuid>.
Key facts:
- The dashboard renders links as https://github.com/copilot/tasks/<uuid>, but the cloud API actually serves sessions at /agents/tasks/<uuid> — the two paths are not equivalent
- API checks (2026-09-09): unauthenticated /agents/tasks/<id> returns 400, authenticated returns 200, while the web route /copilot/tasks/<id> 404s
- The CLI itself prints https://github.com/copilot/tasks/<uuid> after a successful resume, suggesting the client builds URLs from a slug missing the /agents/ prefix instead of deriving them from the real API endpoint
Affected: Copilot CLI 1.0.84-3 (prerelease), latest Chrome on Windows, current github.com web app. The dashboard listed 320 active sessions.
