TL;DR

Check the status page at status.claude.com for any ongoing issues or maintenance that may be causing the 500 Internal Server Error.

Guidance

  • Verify the status of the Claude API at status.claude.com to see if there are any reported issues or maintenance windows that could be causing the error.
  • Since this is a regression and worked in a previous version, try to identify any recent changes or updates that may have caused the issue.
  • Test the Claude Code with a different model or prompt to see if the issue is specific to the Opus model or a more general problem.
  • Consider reaching out to the Anthropic API support team for further assistance, as the error message suggests an internal server error on their end.

Notes

The issue seems to be related to the Anthropic API, and the error message suggests an internal server error. Without more information about the previous working version or any recent changes, it's difficult to provide a more specific solution.

Recommendation

Apply workaround: Check the status page and contact support, as the issue appears to be related to the Anthropic API and not a problem with the Claude Code itself.
