Freemarker The following has evaluated to null or missing

I am getting the below error during the evaluation of the freemarker. However, this error only shows up only in the builds, not in IDE.

{"code":"NoApplicableCode","description":"Error occured processing template freemarkerTest.ftl\nThe following has evaluated to null or missing:\n==> loadJSON

//freemarker function
<#assign keywordsJSON = "${loadJSON('path/to/file/random.json')}">

//function for creating freemarker function
protected void addUtilityFunctions(String baseURL, Map<String, Object> model) {
    model.put("loadJSON", parseJSON());
}

private TemplateMethodModelEx parseJSON() {
    return arguments -> loadJSON(arguments.get(0).toString());
}

private String loadJSON(String filePath) {
    JSONParser parser = new JSONParser();
    try {
            File file = fileFinder.findFile(filePath);
            if (file == null) {
                LOGGER.warning("File is outside of data directory");
                throw new RuntimeException(
                        "File " + filePath + " is outside of the data directory");
            }
            return parser.parse(new FileReader(file.getPath())).toString();
        } catch (Exception e) {
            LOGGER.warning("Failed to parse JSON file " + e.getLocalizedMessage());
        }
        LOGGER.warning("Failed to create a JSON object");
        return "Failed to create a JSON object";
    }

The problem was there were different functions for different freemarker templates. I did not put the function to the correct place. All syntax and the function calling is true in the question.
