Description

I've an application using the ajax call in the combox onchange event. When the function was called, return a 404 browser's message. The browser's stack trace:

**send** https://code.jquery.com/jquery-3.5.1.js:10099:10
**ajax** https://code.jquery.com/jquery-3.5.1.js:9682:15
**carregaComboAtivoAjax** http://localhost:8080/SSP/bootstrap/js/funcoes.js:6:7
**onchange** http://localhost:8080/SSP/cadCadastraCampo:1:22
**receiveMessage** resource://gre/actors/SelectChild.jsm:271:21
**receiveMessage** resource://gre/actors/SelectChild.jsm:471:21

1. My js ajax function:

1 function carregaComboAtivoAjax(url) {
2    var uoId = document.getElementById('idUo').value;
3    $.ajax({
4        type: 'get',
5        url: url,
6        dataType: 'html',
7       data: { uoId: uoId },
8       success: function(data) {
9            if (data != null) {
10                $("body").html(data);
11            }
12        }
13    });
14 }

2. My Spring Boot - Controller:

@RequestMapping(value = "./carregaComboAtivoCadastraCampo", method = RequestMethod.GET)
	public String carregaComboAtivo(@RequestParam UUID uoId,  Model model) {
          ....
}

• What do you expect to happen? I expect the URL call my controller methods (iten 2);

• What actually happens? I debug my ajax function in the console.log, and in the line 3, the $.ajax({ command stop working. I read some stack overflow community post that suggest to use the fisical file jquery.3.5.1 insetead of CDN url. I changed and the problem persist. I'm using jquery.3.5.1.js and jquery.3.5.1.min.js (CDN url in the head tag) + Spring Boot + Bootstrap + thymeleaf + Firefox Browser.
  The 404 is fake, because the URL is corret: http://localhost:8080/SSP/carregaComboAtivoCadastraCampo?uoId=ce83ca47-6b29-4878-98ee-6c0cb1a1cf66 and is calling the js function carregaComboAtivoAjax(url);
  In the POM.xml there is not expliced dependecy, because my application is war.

• Which browsers are affected? Yes, the browser is affected. In the browser stack trace, I see the code lines that represente a exception code. I openned a bug issue in the firefox. However, I need to descart the jquery issue.

Link to test case

http://localhost:8080/SSP/cadCadastraCampo
P.S: Our application is in test and the code is protected. I can not share a public URL. But I think with the browser stack trace, it will possible to find the mistake.

Thanks for wall,
Best,
