I've read on our.umbraco.org that the Umbraco Forms' "file upload" can be used to upload images that can then be used by the media picker.
I've created a workflow which creates an Umbraco document, and I mapped the file upload to the document type's media picker and all the other properties are of course mapped as well.
Whenever I submit the form, it creates the unpublished node as it should, and it maps all the properties EXCEPT the media picker. I can't figure out why...
I'm on Umbraco version: 7.3.7.
Thank you in advance.
