[Copilot]

The cleanup_file function does not check if fileInfo is undefined before accessing fileInfo[0], which could lead to a runtime error if no matching file entry is found. Consider adding a check to ensure fileInfo exists before attempting deletion.

Suggested change

	let fileInfo = filesInfo.find(f => f[1] === path);
	let fileInfo = filesInfo.find(f => f[1] === path);
	if (!fileInfo) {
	console.warn(`No matching file entry found for path: ${path}`);
	return;
	}
