Square WebPay support thread.

[carlwhat]

i have not seen this error.

it will be a tricky one to figure out as the error is coming from the square SDK.

you could try changing line 108 from includes/modules/payment/square_webPay/square/square/src/ApiHelper.php as below, but it is a pure guess on my part.

//from
public static function serialize($value): string
//to
public static function serialize($value): ?string 

and i'm unsure what else that might affect.

best.

i am also coming back to my attempted solution here. have you tried it?

i have done some debugging, and it looks like the serialize function is taking the array of the whole order.

the problem is something in the array is not in utf8 encoding. so the most likely culprit is the japanese product name. it is NOT the <br /> in the product name string.

i would check the encoding of the product name that you think is causing the problem. i am not the character encoding king, nor do i fully understand it. but that's my guess.

we could add some checking to get the last error if you are so inclined. but i am curious about my other questions on this issue.

best.
