TypeError: quote_from_bytes() expected bytes on mocker.spy

When i'm trying to mock a stripe function, i get the following trace.

resources/payments/tests/test_webhooks.py:122: in test_subscription_updated_trial

    raise TypeError("quote_from_bytes() expected bytes")

This is the way i call it
spy = mocker.spy(stripe.Subscription, "delete")

Note you are not mocking it, you are using mocker.spy, which still calls the original function. Did you mean to use mocker.patch.object instead?
