Error: "The property LengowAddress->dni is empty"
Problem: > You encounter this error in the Lengow Toolbox when trying to synchronize your orders. It means PrestaShop is blocking the order creation because it requires a Tax ID (DNI) for the customer's country, but this information is missing from the marketplace.
Solution: > You need to disable the Tax ID requirement for the affected country in your PrestaShop back office:
In your left menu, go to International > Localization.
Click on the Countries tab at the top.
Click on the relevant country (e.g., France) to edit its settings.
Scroll down and set the Does it require a tax identification number? toggle to No.
Save your changes and restart the order synchronization in the Lengow Toolbox.
