Hi, there. I am using Odoo community version 10. After to do some testing activities with the inventory module. I decided to uninstalled and re installed it again. After that, I tried to create a stockable product. However, when I wanted to clic the update the number of pieces of this item the system sends the followind error.

Traceback (most recent call last):

Any idea how to fix it.
