Why is the setup_future_usage attribute missing in Stripe payments?

[prav2019]

We have configured Stripe as our payment gateway. We are also creating customer account in Stripe. Until few weeks back, we were getting setup_future_usage in POST /v1/payment_intents, Hence we could attach card to the customer later. DOn't know what happened, now we are not receiving this attribute in request and we cannot attach card without that.
