I\'m seeming to have an issue with FormData being null. I\'m trying to upload files and JSON in a single POST request. I\'ve tried a variety of things, but nothing has seemed to

Okay I have same problem and I think know the solution after I read this documentation from MDN.

I fix it with this way:

var formData = new FormData();
// After instantiate the object we should use append method
// And append more data as you needed with this way:

formData.append('prices', $("#columnPrices").val());
formData.append('id', $("#columnIds").val());
formData.append('file', $("#uploadCSVWithData");

$(this).html('');
$.ajax({
    type: "POST",
    url: '{removed}',
    data: formData,
    success: function(done) {
        $("#submitCSVForUpload").html("Submit");
        $("#uploadFromCSVModal").modal('hide');
    },
    processData: false,
    contentType: false
});
