TL;DR

Downgrade to version 2.0.45 of the Claude Code extension to potentially resolve the API Error 500 issue.

Guidance

  • The error message suggests an internal server error, but since it's a regression and worked in a previous version, it might be related to the update.
  • Try downgrading the extension to the last known working version (2.0.45) to see if the issue persists.
  • If downgrading resolves the issue, it could indicate a problem with the latest version of the extension.
  • Check the status.claude.com page for any ongoing issues or maintenance that might be causing the error.

Example

No code snippet is provided as the issue seems related to a versioning problem rather than a coding error.

Notes

The solution is based on the information that the issue is a regression and was working in version 2.0.45. If downgrading does not resolve the issue, further investigation into the extension's updates or the Anthropic API might be necessary.

Recommendation

Apply workaround: Downgrade to version 2.0.45, as it is the last known version where the functionality worked correctly, and the current version is causing a regression.
