Delivery customization function suddenly stop working

[bithaolee]

One of my customers uses my app, and today the delivery customization function suddenly didn't work, I tested the checkout in his store, but I can't see the execution log in the Shopify Partner backend management system, I checked the customer through the API (deliveryCustomizations), the status is active, there is no problem, it just doesn't work, I don't know what to do, has anyone encountered the same problem with me?
