Send file by Ajax and FormData fail

Question

I'm trying to send a file using Ajax in Jquery creating a FormData previously. This is my code:

var inputFileImage = document.getElementById('uploadImage');
var file = inputFileImage.files[0];
var data = new FormData();                  
data.append('archivo',file);

jQuery.ajax({
    url: '/services/rpc.php',
    type: 'post',
    data: {functionName: 'saveProfileImage', data : data},
    contentType:false,
    processData:false,
})
.done(function(response) {
    alert(response);            
}.bind(this))
.fail(function(response) {
     alert('Sorry, there was an unexpected error, please try again later.\n\nInformation about the error:\n'+response);
        });

This ajax always goes to the fail function, and if I change the processData to true returns my another error saying

Thanks for your help!

processData has to be off to send binary data. The FormData element is completely used as binary data, while data:{} needs to be processed. Additional parameters have to be appended to the formData in this case!

var data = new FormData();                  
data.append('archivo',file);               
data.append('functionName','saveProfileImage');

jQuery.ajax({
    url: '/services/rpc.php',
    type: 'post',
    data: data,
    contentType:false,
    processData:false,
});
