extent analysis

TL;DR

The issue might be resolved by adjusting the stream idle timeout settings or checking the Anthropic API connection stability.

Guidance

  • Verify the Anthropic API connection is stable and not causing the stream idle timeout error.
  • Check if there are any updates or patches for the Claude Code version 2.1.116 that may address the regression issue.
  • Test the ultrplan session in a different terminal or environment to isolate if the issue is specific to the VS Code integrated terminal.
  • Consider reaching out to the Anthropic API support for assistance with the stream idle timeout error.

Notes

The lack of information about the last working version and additional details limits the ability to provide a more specific solution.

Recommendation

Apply workaround: Adjust the stream idle timeout settings or check the Anthropic API connection stability, as the root cause of the issue seems to be related to the API connection or the ultrplan session configuration.
