How to upload with Jquery - Ajax - Webservice

Question

Good afternoon guys, I’m having a hard time uploading a file to the server.

I have tested locally and managed to accomplish successfully both on my machine running by the project and on the server published on IIS 10.0. The problem arises when I try to upload a file through my machine, in the application published on the server. Follow the codes I’m using. The error that returns is 500 Internal server error.

JS

function uploadCaminhoArquivo() {
        var btnUpload = document.querySelector("#btnUpload");
        var btnUploadx = document.querySelector("#btnUploadx");
        var dadoUpload = document.getElementById("dadoUpload").files[0].name;
        var tipoaviso = document.getElementById("ddlTipoAviso").value;
        
        var path = dadoUpload;
        var dataForm = new FormData();
        var fileUpload = $('#dadoUpload').get(0);
        var files = fileUpload.files;
        dataForm.append(files[0].name, files[0]);
        dataForm.append('id', id);
        dataForm.append('tipoaviso', tipoaviso);
        $.ajax({
            type: "POST",
            url: "Gerencial.asmx/criarDiretorio",
            data: dataForm,
            contentType: 'multipart/form-data',
            processData: false,
            success: function () {
                console.log("sucesso");
            },
            error: function () {
                console.log("erro");
                $("#msgErrAnexo").fadeIn(500).delay(1000).fadeOut(500);
                dadoUploadX.style.display = "none";
                btnUpload.style.display = "block";
                btnUploadx.style.display = "none";
            }
        })
    }
