There was an error adding this card error on Testing Payments

[bitcoinagora]

Hi,

I’m having the same issue.

I have test mode on, i want to test Shop Pay, but i’m getting the same error msg “There was an error adding this card” in every situation, either using cards for successful or failed transactions.

Any ideas or solutions?

Thanks.
