Error message

What it means

Wrapping error from parseURLs: reading the URL list file (fv.URLsFile) via parsers.ReadLinesFromFile failed, and the underlying error is reported through the i18n message config_read_urls_failed with the file path and cause. It fires only in the file branch, never for command-line URLs (those are silently skipped if empty).
