I get this error
Yes, I followed the guide which I can't link here. I added to refpackageitem, refScrapofItem, RefShopgoods, and RefPricePolicyofitem. Both server/client side.
but I still get this error.
EDIT: Pls close it; the issue to fix this is to use the RefShopGen Tool. I don't really see a differences, but I think it's case sensitive that is causing the issue when adding items.
