I'm getting the following error while configuring  SaaS on my server using script.

Traceback (most recent call last):
File "saas.py", line 199, in main

xmlrpc.client.Fault: <Fault 2: "Object auth.oauth.provider doesn't exist">

but i have tried with different versions of oauthlib (old and latest) but none of it seems to solve the issue. 

odoo version - 12.0

saas version - 12 .0
