TL;DR

The most likely fix is to investigate and resolve the "Not connected" errors and lock acquisition failures in the application.

Guidance

• Investigate the cause of the "Not connected" errors, which appear to be related to the callTool function and request method in the cli.js file.
• Check the application's connection settings and ensure that it is properly configured to connect to the required services or APIs.
• Look into the lock acquisition failures, which may be related to multi-process scenarios, and consider implementing a retry mechanism or adjusting the locking mechanism to handle such scenarios.
• Review the application's error handling and logging to ensure that it is properly handling and logging errors, and consider adding additional logging or debugging statements to help diagnose the issue.

Example

No specific code example can be provided without more context, but reviewing the cli.js file and the callTool and request functions may be a good starting point.

Notes

The provided error messages are truncated, which may limit the ability to provide a more specific solution. Additionally, the issue may be related to a specific version of the application or a particular configuration, which is not specified in the provided information.

Recommendation

Apply a workaround by investigating and resolving the "Not connected" errors and lock acquisition failures, as this is likely to be the root cause of the issue. This may involve modifying the application's connection settings, adjusting the locking mechanism, or implementing a retry mechanism to handle temporary connection issues.
