ReferenceError: L is not defined

After install Erpnext from “develop” branch, I choose Agriculture module during configuration step.
So I started to navigate on my ERP app: everything is ok
Now, when I go to Agriculture module to create a location I got a blank page. And when I check my console log dev tool, I said “ReferenceError: L is not defined”. It seems the plugin leaflet is not loading.

Can you help me please.

I am also having same issue, any solution?
