Unable to cancel subscription from Stripe

[Synthmax]

When I cancel a subscription for a user from the stripe dashboard
https://dashboard.stripe.com/test/customers -> some customer

the webhook is called ok. but i get this error
NameError - uninitialized constant Sale:
config/initializers/payola line 5
sale = Sale.find_by(stripe_id: event.data.object.id)

The implementation example from https://github.com/peterkeen/payola/wiki/Configuration-options
is slightly different

Payola.configure do |payola| payola.subscribe 'charge.succeeded' do |event| sale = Sale.find_by(stripe_id: event.data.object.id) SaleMailer.admin_receipt(sale.guid) end end

but gives the same error
I have been looking in the schema and can see the schemas created by the payola gem

After following the tutorial to the letter, I downloaded the example code, same problem

This problem has been fixed, and the new RSpec tests will be rolling out in over the next
however many days, including all the Stripe and Payola type tests.
