Attempt to make any amount of payment through Hitpay Wix integration results in an error popup stating "The order amount is too small or large to process. Add more items or split your order into multiple purchases". The error makes it impossible for customers to proceed to the payment gateway. This error is not reproduced when HitPay integration is turned off and manual payment is turned on, so it seems that the issue lies with HitPay's API response upon clicking "proceed to pay with HitPay". Please advise.

(This issue only popped up on 17 July and there was no issue on 16 July and before).
