best.
Since I can not reproduce the error, I can only hope to see the error live on the "Whos online" list of active customers.
I just had another customer who was stuck at squareWebPay_handler.php for 30s.
It seems he went then back to checkout_confirmation and then was able to finish the credit card transaction. No error in the logs.

I think something is wrong on Square's or Square Japan's side.
