I have created a system user with no role except System Manager.
After log in, this user can’t open the form from custom app. Also can’t save a new doc (blank form is still displayed).
But when click on a doc, the form is a page with blank cards.
The doc list also not displayed correctly - no side bar and no search box etc.
In the browser console there is error msg:
Unhandled Promise Rejection: TypeError: undefined is not an object (evaluating 'this.sidebar.add_user_action')
But when I assign the Translator role, it can open the doc form normally.
So I think this is a bug. Can anyone confirm this?
