TL;DR

The issue is likely related to a regression in the Claude Code version 2.0.109, and a potential fix or workaround may involve investigating the changes made in this version or rolling back to a previous working version.

Guidance

  • Investigate the release notes or changelog for version 2.0.109 to identify potential changes that may have introduced the regression.
  • Check the status page at status.claude.com for any known issues or maintenance that may be causing the API error.
  • Since this is a regression, try to identify the last working version and compare its behavior with the current version to isolate the issue.
  • Consider reaching out to the Anthropic API support team for further assistance, as the error message suggests an internal server error.

Notes

The lack of information about the last working version and additional details about the error makes it challenging to provide a more specific fix. The issue may be related to a specific change in the Claude Code version 2.0.109 or an issue with the Anthropic API.

Recommendation

Apply workaround: Since the issue is a regression, it's likely that a previous version of Claude Code worked correctly. If possible, try rolling back to a previous version or waiting for an update that addresses the regression.
