Error when uploading file

Question asked by dsicpam84 on Nov 26, 2018
Latest reply on Nov 30, 2018 by tasse007

Hello,
I'm an unexperimented user on activiti.
I deployed a fresh new Activiti 6.0 which seems to work fine.
But I have an error when trying to upload a file on a simple form.
GUI says "an error occured" and looking at the ajax request, I get the error below.
I'm sure it's just a simple thing I'm missed in the configuration but I can't find it.
Thanks in advance for your help.
