Odoo.sh install fails on website_sale.tests module

I have this Odoo theme with a couple of custom apps made for a company I'm working for, everything works great on my local machine as I expect It, but when I push the code to Odoo.sh, I get the following on the logs and the install fails:

What I noticed however is that on the development stage I can run the code and everything works like on my local machine, but when I move it to the staging stage, It returns a fresh Odoo installation.

Any help would be appreciated.
