TL;DR

The issue is likely related to a regression in the Claude Code version 2.1.109, causing an API Error 500 when sending a message.

Guidance

  • Verify that the issue persists when sending different types of messages to isolate if it's message-specific or a general API issue.
  • Check the Claude Code changelog for any known issues or regressions introduced in version 2.1.109.
  • Attempt to reproduce the issue using a different Claude Model, if available, to determine if the problem is model-specific.
  • Monitor the status.claude.com page for any ongoing maintenance or issues that might be contributing to the error.

Notes

The lack of information about the last working version and additional details limits the ability to provide a more specific fix. The guidance provided is based on the assumption that the issue is related to the regression mentioned.

Recommendation

Apply workaround: Since the issue is likely a regression, waiting for an update or fix from the developers might be the best course of action. In the meantime, exploring alternative models or versions could provide a temporary workaround.
