LOCAL_FILE_FILESYSTEM_ERROR

Error message

Error listing files in directory: " + location

What it means

DataLocation.files() hit an IOException while opening a DirectoryStream over the location with the glob pattern; directory listing itself failed (permissions, concurrent removal, or filesystem error) and the exception is wrapped into this error.
