Do Spine-Leaf architectures need STP?

I started working with mininet and I decided to implement a spine-leaf architecture and as far as I knew Spine-Leaf architectures do not need any loop preventing algorithm. I also read it in this article https://www.arubanetworks.com/spine-leaf-architecture/

The problem is that if I don't use a controller with STP enabled I cannot reach host to host. I can communicate between hosts and leafs or spines but not host to host. Anyone knows why it happens? Why I need to enable STP?
