TL;DR

The most likely fix is to authenticate with a Claude.ai account using the /login command, as API key authentication is not sufficient for Claude Code web sessions.

Guidance

• Run the /login command to authenticate with a Claude.ai account, as suggested in the error message.
• Check the authentication status using the /status command to ensure that the authentication is successful.
• Verify that the Claude Code version (2.1.91) is compatible with the current authentication requirements.
• If issues persist, consider seeking support from the Claude Code team, providing the Feedback ID (e9858517-7900-4bb2-ab40-6552295e9958) for further assistance.

Notes

The error messages indicate a specific issue with authentication, and resolving this may address the reported problems with Claude Code's performance and functionality.

Recommendation

Apply the workaround by running the /login command to authenticate with a Claude.ai account, as this directly addresses the error message and may resolve the reported issues.
