Hi, I am getting an unknown error. Whenever I try to create a billing attempt, I get PAYMENT_PROVIDER_IS_NOT_ENABLED error. When I create a billing attempt, only values I pass in is contractId and idempotencyKey. Does the API subscriptionBillingAttemptCreate chck payment providers with contract's default payment method? Or how does it check payment provider?
I'm supposing it's not using default payment method because it looks like default payment method is set up correctly.
