If a directory tag OSMTemplate is not empty but doesn't contain the expected line StoreName xxx, then Webdav door will return error 500 without details and log message. With higher debug lever one can get more information, which is still quite cryptic:

One is to remove such a 'bad' directory from the listing and rise an alarm:

} catch (CacheException e) {
  LOGGER.error(AlarmMarkerFactory.getMarker(PredefinedAlarm.INACCESSIBLE_FILE,
                  "namespace"),
          "Failed to retrieve file attributes {} : {}",
                           entry.getStat().getId(), e.toString());
}
Failed to retrieve file attributes 00007FE77774C27B4EF6BB08D509FFE393BE : CacheException(rc=37;msg=StoreName not found in template)
