Hi Liam, first let me thank you for your time. The relationship in Videoconference is written using the explicit string form because at first I thought it could be a circular import problem, but it could be written as User without affecting the problem positively.
I'll try to init the form class as suggested and see if it makes the error disappear and I'll let you know.
