Build Fix Log - Digital Product Webhook Handler

Issue​

Error: AspectJ compilation error in DigitalProductPaymentWebhookHandler.java

The method findByOrderId(UUID) is undefined for the type LineItemService
at line 143

Root Cause​

The webhook handler was trying to call lineItemService.findByOrderId(order.getId()) but this method doesn't exist in the LineItemService class.

The issue was a design mismatch:

  • ❌ Attempted: Query LineItems independently via a non-existent service method
  • ✅ Correct: Access LineItems directly from the SalesOrder relationship

Solution​

Changed the approach to use the SalesOrder's embedded relationship:

Before (❌ Broken):

List<LineItem> allLineItems = lineItemService.findByOrderId(order.getId());

After (✅ Fixed):

List<LineItem> allLineItems = order.getOrderItems() != null ? order.getOrderItems() : List.of();

Why This Works​

The SalesOrder model (generated via ThorAPI) contains:

  • Field: orderItems - direct relationship to List<LineItem>
  • Method: getOrderItems() - access the line items
  • Method: setOrderItems() - set the line items

This is a one-to-many relationship managed by JPA/Hibernate.
