Lua Lua Script Error : 'doNpcSellItem' (a nil value) : When trying to purchase something from a merchant

[eupharias]

Hey guys, I'm looking for some help with an error that I'm getting.

TFS Version
1.4.2

Recreate
Attempt to buy something via a merchant NPC's 'trade' interface.

Error

Lua Script Error: [Npc interface]
(Unknown scriptfile)
data/npc/lib/npcsystem/modules.lua:989: attempt to call global 'doNpcSellItem' (a nil value)
stack traceback:
        data/npc/lib/npcsystem/modules.lua:989: in function 'callbackOnBuy'
        data/npc/lib/npcsystem/npchandler.lua:263: in function 'processModuleCallback'
        data/npc/lib/npcsystem/npchandler.lua:461: in function 'onBuy'
        data/npc/lib/npcsystem/modules.lua:1089: in function <data/npc/lib/npcsystem/modules.lua:1089>

Info
This error is preventing the ability to purchase anything from merchants. The merchant won't reduce the amount of gold in the player's inventory, and won't add the items to the player's inventory as a result.

Any help is appreciated!

You don't have this function declared in your base.
It can be either via script or in the source, look for it in the datapack you got.

Look here: forgottenserver/npc.lua at 0e20d54eebc6be8ea7ed50d0fd3d31d5d43df1f9 · otland/forgottenserver (https://github.com/otland/forgottenserver/blob/0e20d54eebc6be8ea7ed50d0fd3d31d5d43df1f9/data/npc/lib/npc.lua#L13)

that function exists in TFS, probably you are mixing datapack from other engines with TFS.

I've actually reverted back to TFS 1.4.0 for now to solve the issue. I plan to tinker with it more in the future, likely starting with a fresh install. Appreciate the help, guys.

I'm having issues with the npcs. I can't buy items through the trade function and some don't spawn. Exactly which files do I need to replace out of this data pack?

Also If I extract the hole thing and overwrite the previous files I cannot log into the game.

here are the errors i get.
