Type error: Argument 4 passed to PrestaShop\PrestaShop\Core\
When you access the order, you may see the following critical error expecially you migrate a database from one to another with different version mysql or mariadb. Below are the reasons why you caught this error. I got the below statements from MatShir from github.
- If you upgrade from older versions of Prestashop. They saved the empty values as
NULLs instead of''. The old product page and old order page could work with it, the new product page and migrated order page don't. - If you backup your DB using backoffice and restore it. Then all fields that were
''are exported asNULL. - If you use some module that doesn't put
''to optional fields but leaves themNULL.
