WoWInterface - SetMap - Addon Assitance

I currently have an addon which is throwing up errors it appears to be related to the fact it can't set the map/get the map ID.

The code I have for this portion is like this;

Code:

function MountManager:ZONE_CHANGED_NEW_AREA()

        if not InCombatLockdown() then

                SetMapToCurrentZone();

                state.zone = GetCurrentMapAreaID()

        end

        

        self:UpdateZoneStatus()

end

function MountManager:UpdateZoneStatus(event)

    if InCombatLockdown() or state.inCombat or state.inPetBattle then return end

    

    local prevSwimming = state.isSwimming

    local prevFlyable = state.isFlyable

    

    state.isSwimming = IsSwimming() or IsSubmerged()

    

        local usable, _ = IsUsableSpell(flightTest)

    if IsFlyableArea() and self.db.char.mount_skill > 2 and usable == true then

        state.isFlyable = true

    else

        state.isFlyable = false

    end

    

    if (prevSwimming ~= state.isSwimming) or (prevFlyable ~= state.isFlyable) then

        self:GenerateMacro()

    end

end

I'm not sure if its SetMapToCurrentZone or GetCurrentMapAreaID that needs updating, I tried changing to C_Map.GetAreaInfo but I still get this error;

Code:
