GetAbilityCost returns nil for power type

[LadyTiny]

I've tried using GetAbilityCost, GetAbilityCostOverTime, and GetSlotAbilityCost. All three of them return the the first argument, for example 3500 for cost, but the second argument is always nil.

local cost, mechanic = GetAbilityCost(abilityId)

Mechanic is always nil. Is there any other way to find out whether an ability is a magicka or stamina or health costing ability?

GetAbilityCost does not return 2 values! It only returns 1 -> the costs (number).
It got 4 parameters where the 2nd is the mechanicFlag you need to pass in to the function.

GetAbilityBaseCostInfo coud be the one you are searching for, as it will return as 2nd return value the CombatMechanicFlags

--- @param abilityId integer
--- @param overrideRank integer|nil
--- @param casterUnitTag string
--- @return integer|nil baseCost, CombatMechanicFlags|nil mechanicFlags, boolean|nil isCostChargedPerTick
function GetAbilityBaseCostInfo(abilityId, overrideRank, casterUnitTag) end

--- @param abilityId integer
--- @param mechanicFlag CombatMechanicFlags
--- @param overrideRank integer|nil
--- @param casterUnitTag string
--- @return integer cost
function GetAbilityCost(abilityId, mechanicFlag, overrideRank, casterUnitTag) end

Those api funtions, their parameters and return values, and the enums like CombatMechanicFlags can be found in the API funtions list:
