It looks like this happens when using the "Check out with PayPal" button on the shopping cart when no account is created. Using that button takes me to PayPal. I noticed it does not pass any shipping or tax information, then when you click continue to review order on PayPal, the error is generated and the "Warning: an error occured, please let us know" page displays. The customer shows the charge pending on their account, but I don't have anything pending on my end. The error generated is as follows.

I've been needing to upgrade my PHP to 8.0 so I will do that to see if it still produces this error and will reply once I test.
