TL;DR

The issue seems to be related to errors and timeouts in the tool execution, and a potential fix could be to adjust the search path or pattern to make it more specific.

Guidance

• The RipgrepTimeoutError suggests that the search is taking too long, so try to narrow down the search path or pattern to reduce the execution time.
• The McpToolCallError indicates a validation error, which might be related to the input parameters; double-check the input values and ensure they match the expected format.
• The Error: Request was aborted could be a symptom of a larger issue, but it might be worth investigating the request timeout settings to see if they can be adjusted.
• Given the truncated content, it's essential to review the full error log to identify any recurring patterns or errors that might point to a specific root cause.

Example

No specific code snippet can be provided without more context, but adjusting the search path or pattern might look something like this:

# Example of narrowing down the search path
search_path = "/specific/directory"

Note that this is a highly hypothetical example and may not directly apply to the issue at hand.

Notes

The provided information is incomplete due to truncation, which limits the ability to provide a precise fix. The errors seem to be related to tool execution and timeouts, but a more detailed analysis of the full error log is necessary to determine the root cause.

Recommendation

Apply a workaround by adjusting the search path or pattern to make it more specific, as this might help mitigate the RipgrepTimeoutError and potentially other related issues.
