On clover Flex.Refund via PaymentConnector.refundPayment.
This might be our app bug. But we weren't sure as this message didn't indicate if it was duplicate (refund more than original Order). What I'm trying find is when / what cases is this error message returned?
What environment? Sandbox? Region? US/Canada? How/when are you performing the refund. Is it a partial or full refund? I believe this error can occur if the transaction is still pending.
