Fix InvalidPathException

✅ Solution

InvalidPathException in filebeat/logstash configurations often stems from platform-specific path separators (e.g., "\" on Windows vs. "/" on Linux) or incorrect escaping of special characters. To fix it, ensure path configurations use cross-platform path separators (ideally "/") and properly escape any backslashes needed literally within the path string, such as using double backslashes ("\\\\"). If unit testing is involved, use `Paths.get()` to construct paths correctly for the running OS using relative paths.
