According to the example (line 65) in your modules.lua it should be "promotions" not "promotion" and it should be a table:
promotions = {[1] = 5, [2] = 6, [3] = 7, [4] = 8}
Maybe try that?

This is our working one.

local keywordHandler = KeywordHandler:new()
local npcHandler = NpcHandler:new(keywordHandler)
NpcSystem.parseParameters(npcHandler)

function onCreatureAppear(cid)       npcHandler:onCreatureAppear(cid)       end
function onCreatureDisappear(cid)     npcHandler:onCreatureDisappear(cid)       end
function onCreatureSay(cid, type, msg)     npcHandler:onCreatureSay(cid, type, msg)     end
function onThink()         npcHandler:onThink()           end

local node1 = keywordHandler:addKeyword({'promotion'}, StdModule.say, {npcHandler = npcHandler, onlyFocus = true, text = 'I can promote you for 20,000 gold coins. Do you want me to promote you?'})
  node1:addChildKeyword({'yes'}, StdModule.promotePlayer, {npcHandler = npcHandler, cost = 20000, level = 20, promotion = 1, text = 'Congratulations! You are now promoted.'})
  node1:addChildKeyword({'no'}, StdModule.say, {npcHandler = npcHandler, onlyFocus = true, text = 'Alright then, come back when you are ready.', reset = true})

npcHandler:addModule(FocusModule:new())
