I received this error when trying to type in a credit card number. I'm curious if it's the CVV that is incorrect or not.
I think that is likely based on the message being displayed. It would be helpful if you could provide some details such as what environment you are in (sandbox, production) and what type of card you used (and the number if using a test card). You may want to try a test card from here - https://docs.clover.com/docs/test-card-numbers (if you are in sandbox).
