At our client, we are building a solution with Nintex Workflow and Nintex Forms On-Premises (2013).
I've adjusted the NewForm of a Document Set with Nintex Forms (using the Responsive Form), which works great! However, when I try to use the Nintex Form WebPart on a SharePoint Page, I receive an error while submitting the form.
Sorry, something went wrong
To add an item to a document library, use SPFileCollection.Add()
The form is loaded correctly and works fine, except it isn't submitting. I've tried different Redirect URL's and-/or settings related to the List Form WebPart Confirmation Message, but no luck.
Am I missing something here?
