NullReferenceException when accessing Catalog content items after upgrade to commerce 7.12 (latest 7.x version)
I wanted to help but 7.12 is just too old for me to provide any helpful suggestion. Mind you it's 4 years old now. If you can (convince your boss), I would suggest to try to upgrade to latest version.

After upgrading the CMS to 7.19 and Commerce to version 7.12, it all works perfectly except when trying to access the catalog items. This happens either when using the API (code below), as well as through the Commerce Catalog backoffice page.
The error is the following:
[NullReferenceException: Object reference not set to an instance of an object.]
EPiServer.Commerce.Catalog.Provider.Construction.CatalogPropertyLoader.AddSeoPropertyValues(CatalogItemSeoRow seoRow, NodeContent content) +81
EPiServer.Commerce.Catalog.Provider.Construction.CatalogPropertyLoader.LoadProperties(CatalogNodeRow nodeRow, CatalogItemSeoRow seoRow, NodeContent content) +150

It looks to be a data issue. Has this happened to anyone?
