File upload results in an error - net::ERR_FAILED while uploading word file

Question

This is my code:

var formData = new FormData();
var f = $("#myFile")[0].files[0];

var form = $('#__AjaxAntiForgeryForm');
var token = $('input[name="__RequestVerificationToken"]', form).val();

formData.append('__RequestVerificationToken', token);
formData.append("fileUpload", $("#myFile")[0].files[0]);
$.ajax({
    url: '/GenAI/GetDataFromFile',
    crossDomain: true,
    type: 'POST',
    contentType: false,
    processData: false,
    cache: false,
    data: formData,
    beforeSend: function (xhr) {
        xhr.setRequestHeader('Access-Control-Allow-Origin','*')
        xhr.setRequestHeader("XSRF-TOKEN",$('input:hidden[name="__RequestVerificationToken"]').val());
    },
    success: function (response) {
        alert(response);
    },
    error: function (err) {
        alert(err.statusText);
    }
});
