I am creating a subscription flow for a product plan.
All the subscription process is done by REST APIs.
But at the time when i proceed to subscribe after clicking `Login to subscribe button`, i am facing an error at the redirected page
with message Things don't appear to be working at the moment. Please try again later.
page URL is : https://www.sandbox.paypal.com/webapps/billing/subscriptions?ba_token=BA-6RL60762NP651641S
In console it gives error:
{"ack":"contingency","contingency":"VALIDATION_ERROR","meta":{"calc":"......","rlog":"......"},"server":"......."}
What is the real problem here?
