TL;DR

Try starting a new session as suggested in the error message to potentially resolve the issue with setting up the git_repository source.

Guidance

  • Verify that the GitHub repository is correctly set up and accessible, as the error mentions an issue with the git_repository source.
  • Check the session ID provided (https://claude.ai/code/session_01TPSg8FtsEFh4Cazy5e2YZB) for any additional error details that might be logged, which could help in diagnosing the issue.
  • If starting a new session does not work, consider contacting support with the session ID for further assistance, as the error message suggests.
  • Ensure that the Claude Code version (v2.1.101) is compatible with the Anthropics API and the Opus model being used.

Notes

The issue seems to be related to the setup of the git_repository source, but without more specific error details or logs, it's challenging to provide a more targeted solution. The fact that this never worked suggests it might be a configuration or compatibility issue rather than a regression.

Recommendation

Apply the workaround of starting a new session as initially suggested by the error message, and if the issue persists, contact support for further assistance.
