Does anyone know about solution? I'm thinking that ZARS Tribal reborn mya be the issue, so I'm going to reload game without it.

Considering that you have not gotten any replies so far, I would recommend going to reddit and asking this question. r/RimWorld has some modders who may know the issue.

[ReZpawner]

It's attempting to generate something with a parameter name that doesn't exist (null error is when you try to pass something to a constructor that doesn't exist), in this case the "type" doesn't exist.
It's definitely a mod error, or everyone would have it. Most likely it's an item that the mod creator figured didn't need a type, as it wasn't supposed to be in trade anyways, but it somehow got loaded into it anyways or just an empty item. I haven't looked into what trade goods are generated, so I wouldn't know how and why certain things are traded, and others aren't, but I'd assume it's a fairly easy fix if you search through the list of items the mod has.

Update: Should be in ModFolder\Defs\TraderStockInjectorDefs if the mods I have are anything to go by. Compare the items added there to their properties and see if there's anything missing.

I could be completely wrong about allt his too though, so checking with the mod creator is probably the better option.
