Weakaura: attempt to compare nil with number

[Louarn]

I am using this bit of code for certain weakauras to shift down when on CD. Yet i keep running into the "attempt to compare nil with number"error in this bit of code.

Any idea what could cause this ?

function(progress, startX, startY, deltaX, deltaY)
    local  ycoord,xcoord
    --Choosing what animation to show and determig start time of animation
    if aura_env.currState == "cd" then
        if aura_env.prevState == "active" then
            aura_env.animstart = GetTime()
            aura_env.animtype = "hide"
        end
        aura_env.prevState = "cd"
    elseif aura_env.currState == "ready" then
        if aura_env.prevState == "cd" then
            aura_env.animstart = GetTime()
            aura_env.animtype ="show"
        end
        aura_env.prevState = "ready"
    elseif aura_env.currState =="active"  then 
        aura_env.prevState = "active" 
    end
    
    if aura_env.animstart and GetTime()-aura_env.animstart>aura_env.animDuration then
        aura_env.animstart = nil
        aura_env.animtype = nil
    end
    
    if aura_env.animstart then         
        local animprogress = (GetTime()-aura_env.animstart)/aura_env.animDuration
        if aura_env.animtype== "hide" then
            ycoord = animprogress*aura_env.deltaY
            xcoord = animprogress*aura_env.deltaX
            WeakAuras.regions[aura_env.id].region.stacks:SetPoint("CENTER", WeakAuras.regions[aura_env.id].region.icon,"CENTER",-xcoord,-ycoord) --Moving text relative to icon so that is stays in place
            return startX+xcoord, startY+ycoord
        elseif aura_env.animtype== "show" then     
            ycoord =(1-animprogress)*aura_env.deltaY 
            xcoord =(1-animprogress)*aura_env.deltaX
            WeakAuras.regions[aura_env.id].region.stacks:SetPoint("CENTER", WeakAuras.regions[aura_env.id].region.icon,"CENTER",-xcoord,-ycoord) --Moving text relative to icon so that is stays in place
            return startX+xcoord, startY+ycoord
        end
    end
    
    if aura_env.currState == "cd"  then
        WeakAuras.regions[aura_env.id].region.stacks:SetPoint("CENTER", WeakAuras.regions[aura_env.id].region.icon,"CENTER",-aura_env.deltaX,-aura_env.deltaY)
        return startX+aura_env.deltaX, startY+aura_env.deltaY
    else 
        WeakAuras.regions[aura_env.id].region.stacks:SetPoint("CENTER", WeakAuras.regions[aura_env.id].region.icon,"CENTER",0,0)
        return startX, startY        
    end
end

EDIT:

This is the error message Bugsack shows me

79518x [string "return function(progress, startX, startY, d..."]:20: attempt to compare nil with number

Line 20. aura_env.animDuration is probably nil.

Cheers for helping ! Sorry i failed to do that. Also here is a link to the full WA: pastebin.com/uv7mhbHp
