Stock Genrator Help

[Omega12]

Im working on a mod that includes a new weapon and I wanted to make a new trader to go with it, as long as some other items, but I get a message in the debug log saying:

"Could not resolve cross-reference: No Verse.ThingDef named (The weapons name which I wont say ) found to give to RimWorld.StockGenerator Thing RimWorld.StockGenerator Thing.

I have no clue what it means, as Ive only created 2 mods. Any help I could get to fix it? Any help is appreciated!
