Class description at the top says:

Prototype of an item. For example, an item prototype can be obtained from LuaGameScript::item_prototypes by its name: prototypes.item["iron-plate"].

The `prototypes.item["iron-plate"]` is correct, but the `LuaGameScript::item_prototypes` is a leftover from the previous version, and the link leads to property that no longer exists. It should probably be replaced with a link to `LuaPrototypes::item`.

Duplicate of 117189, which is to be fixed with next release.

Thanks for the info, I've searched the forums but didn't found that one.

Yeah, you have to use advanced search to search subforums as well as the current forum. Kind of a hassle, but it's how it is.
