Get Parameter from POST request multipart/form-data on Local wokrs

Hello! Basically I have a .jsp let's call card.jsp so there is a form where the user can upload text and pdf, image, audio, so I wrap all those info, in a form created by a aux.js and send it to the same card.jsp using POST method and enctype = 'multipart/form-data'

So when I try to get the params in order to send the request to a controller, all the params are null

On local machines this is fine and its working, when the .war is uploaded to Elastic Beanstalk and all the forms with multipart/form-data are not working well (no error logs exist and no errors on console, simply just refresh the site)

this is the piece of code .jsp

if( request.getParameter("sendRequest") != null && Boolean.parseBoolean(request.getParameter("sendRequest")) ){
				List<Part> archivos = new ArrayList<Part>();
				
				for( Part part : request.getParts() ){
					if( part.getSubmittedFileName() != null && part.getSubmittedFileName() != "" ){
						archivos.add( part );
					}
				}
				
				sendRequest = requestController.crearRequest(
						request.getParameter("requestType"),
						request.getParameter("description"),
						Integer.parseInt(request.getParameter("idTaskCard")),
						archivos);
			}

The .js

const urlParams = new URLSearchParams(window.location.search);
			
			const formularioAEnviar = document.createElement('form');
			formularioAEnviar.action = 'job_card.jsp?idTaskCard=' + urlParams.get('idTaskCard');
			formularioAEnviar.method = 'POST';
			formularioAEnviar.style = 'display: none';
			formularioAEnviar.enctype = 'multipart/form-data';
			
			const requestType = document.createElement('input');
			requestType.type = 'text';
			requestType.value = typeRequest.value;
			requestType.name = 'requestType';
			
			const text = document.createElement('input');
			text.type = 'text';
			text.value = description.value;
			text.name = 'description';
			
			const action = document.createElement('input');
			action.type = 'checkbox';
			action.checked = true;
			action.value = true;
			action.name = 'sendRequest';
			
			formularioAEnviar.appendChild(requestType);
			formularioAEnviar.appendChild(text);
			formularioAEnviar.appendChild(action);
			
			const inputs = document.querySelectorAll('input[type="file"].d-none');
			inputs.forEach( input => {
				formularioAEnviar.appendChild(input);
			} );
			
			document.body.appendChild(formularioAEnviar);
			formularioAEnviar.submit();
