extent analysis

TL;DR

The issue can likely be resolved by adjusting the stream idle timeout setting to allow for longer runs, as the error message indicates a timeout occurred due to a partial response received.

Guidance

  • The error message "Stream idle timeout - partial response received" suggests that the current timeout setting is too low for the longer "work" being performed, causing the connection to idle out.
  • To verify this, try reproducing the issue with a shorter "work" duration to see if the error still occurs.
  • Consider checking the Anthropic API documentation for any settings or configuration options related to stream idle timeouts that can be adjusted.
  • Since this was working in a previous version (1.0.100), it may be worth reviewing the changelog for version 1.0.108 to see if any changes were made that could be contributing to this issue.

Example

No code snippet is provided as the issue does not include specific code details.

Notes

The solution may depend on the specific requirements of the "work" being performed and the capabilities of the Anthropic API. Further investigation into the API settings and the changes made in version 1.0.108 may be necessary to find a complete solution.

Recommendation

Apply workaround: Adjust the stream idle timeout setting to a higher value to allow for longer runs, as this is likely the cause of the error and adjusting this setting may resolve the issue without requiring an upgrade.
