extent analysis

TL;DR

The issue can likely be resolved by checking the Anthropic API for any known issues or updates that may be causing the internal server error.

Guidance

  • Verify that the Anthropic API is functioning correctly and not experiencing any downtime or maintenance that could be causing the 500 internal server error.
  • Check the API documentation for any changes or updates to the version update endpoint that may be causing the issue.
  • Test the version update functionality with a different version number to see if the issue is specific to version 2.50.0 or 2.50.1.
  • Consider reaching out to the Anthropic API support team for further assistance with the issue.

Example

No code snippet is provided as the issue is related to an API error and not a code-specific problem.

Notes

The issue seems to be related to a regression in the Claude Code version 2.1.89, and it is recommended to check the API and its documentation for any updates or changes that may be causing the issue.

Recommendation

Apply workaround: Check the Anthropic API for any known issues or updates and test the version update functionality with a different version number to isolate the issue.
