payment via link error " trying to access array offsety on value of type null

[illnot]

Ive senty a client a payment link they could not pay me due to an error after filling out card and name info. saying  "! Trying to access arrayu offset on value of type null" 

Then i sent myself a payment link and got the same error messege just below the card info. 

How to fix this? What is the cause of error?

Hi @illnot thanks for reaching out and welcome to the Seller Community!

Square Online Checkout links are powered by Square Online, so we recommend checking that the correct settings have been configured here first.

Please check the following on your Square Online Overview page:
 

1. Ensure default custom sync settings are set to automatically add new items to this site.
2. Check your items are set to visible.
3. Check your default fulfillment method settings.

For detailed steps on the above visit this link. 

If those settings are now correct and the link is still showing the error message, we recommend updating your browser or device to ensure you're running the latest version and then re-sending the link. 

As a last resort, we recommend deleting and recreating the link once the above steps have been taken.
