Post full data/spells/scripts/support/summon_creature.lua script?

Be sure opening tag is [CODE=lua] too please, so it has correct syntax highlighting.

temporaly fix i dont know if this is wrong but removed this line and works

    local manaCost = monsterType:getManaCost()
    if creature:getMana() < manaCost and not creature:hasFlag(PlayerFlag_HasInfiniteMana) then
        creature:sendCancelMessage(RETURNVALUE_NOTENOUGHMANA)
        creature:getPosition():sendMagicEffect(CONST_ME_POFF)
        return false
    end

Alright, I checked the sources you say you are running.

The member field exists and is part of a public structure which the Lua env can access and the method is registered. There is no reason your script shouldn't work, unless what is contained in the variable at that point isn't actually a MonsterType.

(also note: Even if you don't have manaCost set in the monster's xml file, the class set's it's default to 0. Your invocation should give you 0 at worst. It's saying MonsterType::getManaCost is nil, not that the returned manacost value is nil)
