**Core**: `fess-crawler/src/main/java/org/codelibs/fess/crawler/`

     *
     * <p>This method is designed to be resilient to malformed robots.txt files.
     * It will parse valid directives and ignore invalid ones, ensuring that partial
     * content can be extracted even from poorly formatted files.</p>
     *
     * <p>The following errors are handled gracefully (line is skipped, parsing continues):</p>
     * <ul>
     * <li>Invalid directive formats</li>
     * <li>Unknown directives</li>

                logger.warn("Failed to access log files.", e);
            }
        }
    }

    /**
     * Gets host information including hostname and IP address.
     *
     * @return formatted string containing hostname and IP address
     */

Let's say you want it to return indented and formatted JSON, so you want to use the orjson option `orjson.OPT_INDENT_2`.

You could create a `CustomORJSONResponse`. The main thing you have to do is create a `Response.render(content)` method that returns the content as `bytes`:

            return ConfigType.DATA;
        }
        return null;
    }

    /**
     * Extracts the actual ID from a config ID by removing the type prefix.
     * Config IDs are formatted as [type_prefix][actual_id], so this method
     * returns everything after the first character.
     *
     * @param configId the configuration ID to process
