Cant proceed at checkout in Sandbox testing

[badarikrishna]

Hi guys, I have been trying to integrate Paypal checkout where I have created a "buyer" sandbox account with money and "facilitator" ssandbox account with money. In the Paypal checkout script in the payment method I have given ClientID of "facilitator" and whenever I click on Paypal button I log in as "buyer" and end up reaching the payment page but however the default linked Debit card is asking for CVV i tried giving all combinations and found the

attached error through which i am unable to proceed further in sandbox testing.

Your help would be appreciable asap.

Regards.

I think u need to login to buyer's account in sandbox.paypal.com and set a CVV number there. Then use same CVV no for actual sandbox test buyer payment.
