Pull Request Overview

This PR enhances the requireFreePort function by improving how the existing local server is closed, adding error handling and logging to prevent potential hangs.

• Added an err parameter to the close callback to catch and log errors when shutting down the server.
• Ensured the promise always resolves, even if an error occurs.
• Applied optional chaining on this.localServer.close.
