Well, #1. The version should be 3 (In the Manifest). It refers to the modding API version, not your mod’s version.
In the item itself…
Number two, the catalog does not go into the components section.
Number 3 You’re missing the entity data section, mob section (goes under components) and stacks info (also under components).
I’d recommend copying the stonehearth.smod, renaming it to .zip, then extracting it. Then you can look at all of the code in the game. For Instance, right now I’m comparing your code to the code for the basic oak log.
I don’t know what you’re trying to make, but I’m guessing it’s simple. Just find an item that’s like what you want to make, and copy it, changing what’s needed.
