"int() argument must be a string or a number, not 'list'" error oracle 12.1 python

[kono10]

When creating an initial migration in a new python project "python manage.py migrate" I get the following error int() argument must be a string or a number, not 'list'. I am using an oracle db version 12.1. I was able to fix the error by chancing line 245 in lib/python2.7/site-packages/django/db/backends/oracle/operations.py

from

def fetch_returned_insert_id(self, cursor):

return int(cursor._insert_id_var.getvalue())

to

def fetch_returned_insert_id(self, cursor):

return int(cursor._insert_id_var.getvalue()[0])
