Hi clment305,
I worked at this for quite a while a few months or so ago and I was not able to come up with a solution to this using GraphQL. I’m interested to know as well. I ended up splitting the upload and entity creation into two parts. In some ways this worked out to have some advantages, but I still would really like to use GraphQL to do this in other parts of the application. Anyway, you are not alone! I’m going to keep an eye out and see if anyone else has ideas.
