Odoo 11 - Server Error (KeyError) when loading the sales page (Sales Management) - odoo

Question

I have installed "Sales Management" app on my Odoo v11 community edition. Everything was working fine until a few days ago. Now whenever I click on the "sales" tab, I get this server error:
Error:
Odoo Server Error

KeyError: 'sale.advance.payment.inv'
The only code change I made was adding an if-else statement in product_template to add a constraint and it was working perfectly fine along with the sales module, but now all of a sudden the sales module throws this exception.
What could be causing this?

Check your manifest.py for dependencies. If you are using a field from another module you must add it.
