Linux Avesta 772 Npc System Problem

[Daniel13]

Hello after power on the server does not appear npcs ;/

Error console :

data/npc/scripts/default.lua:4: attempt to index global 'KeywordHandler' (a nil value)
Warning: [NpcScript::NpcScript] Can not load script. data/npc/scripts/default.lua


Lua Script Error: [Npc interface] 
data/npc/scripts/default.lua

This means it doesn't load the npcsystem scripts. It's possible the directory in the npc.lua (and maybe also npcsystem.lua) isn't correct for your server or isn't there or that the npcsystem scripts aren't added.

dofile(getDataDir() .. 'npc/scripts/lib/npcsystem/npcsystem.lua')

And other errors :
