Hi, I created a simple addUserTest form in the UI designer. It has a JSON object variable with a valid JSON object to create a user. I tested that by POSTing the JSON object directly to the REST identity API. However, when I use the same JSON object in a form a link a POST action to the submit button, the form returns an error that "Id of the item to retrieve is missing in url ". This is an error for the GET, PUT and DELETE methods but not for the POST method. Why do I get this error? Version: 7.0.1 Edition: Community ---

Never mind. The problem is solved already. It seems that the POST function does not work in preview mode. If you add the form to a process however, it all works fine. ---
