I am pushing a small array with an extract base64 string of an image file (around 600kb), but i can't seem to get the progress of the upload to show.
I added an event
on ajax progress "tag"
browser log ajax.progress
this event is not even triggered.
When using ajax request url, the progress shows up fine.
I am posting the data with Content-Type application/json in the header instead of application/x-www-form-urlencoded
Does it got anything to do with that?
