max recursion with use of memoize decorated function

[dmartin35]

When fetching odds from external api
external/odds/betclic/api.py get_odds
we end up with the following error

Exception possibly due to cache backend.
Traceback (most recent call last):

A quick look at the issues on the django-memoize project did not show the same issue listed

Can it be because we're using an outdated version of django ?
