Please have a look at the JavaScript code below.

const locations = /*[[${locations}]]*/ null;
locations.forEach(location => {
    location.description = 44;
    location.lnglat = 127;

    location.fun(); // error
});

description and lnglat are variables from Java list of objects of class 'Location'; fun is a function from this class.

There is no problem assigning values to variables, but I can't call the function fun. Unfortunately, I don't know what the reason is and how can I fix it. In Java, I use Spring Boot and method addAttribute:

@GetMapping("/")
public String homePage(Model model) {
     model.addAttribute("locations", locations());
     return "home";
}
