TL;DR

The issue is likely due to rate limiting or concurrent access errors, and a workaround may involve retrying the operation or adjusting the API request rate.

Guidance

• The error messages suggest a rate limit error (429) and a lock acquisition failure, indicating potential concurrency issues or excessive API requests.
• Verify the API request rate and adjust it if necessary to avoid hitting the rate limit.
• Consider implementing a retry mechanism with exponential backoff to handle temporary failures.
• Check the claude extension configuration and version for any known issues or updates that may address these errors.

Example

No code snippet is provided as the issue is more related to configuration and API usage.

Notes

The provided errors and environment information suggest a complex issue that may require adjustments to the claude extension, API request handling, or system configuration.

Recommendation

Apply workaround: Implement a retry mechanism with exponential backoff to handle temporary failures and adjust the API request rate to avoid hitting the rate limit, as the root cause seems related to concurrency and rate limiting.
