Client deactivation w/ Stripe throwing error

I am using your stripe integration. I just tried to cancel. I got this

Unrecognized request URL (GET: /v1/customers/xxxxxxxx/subscriptions/). Please see https://stripe.com/docs or we can help at https://support.stripe.com/.

I'm not sure if the cancellation failed and I need to handle it in Stripe? In fact, I just checked and it looks like it didn't cancel in Stripe.
