Describe the bug
On the french version of the game, when calling the function WeakAura.GetAuraTooltipInfo withing the graphic custom text as follows :

local name = GetSpellInfo(269279)
local tooltipText, debuffType, tooltipSize = WeakAuras.GetAuraTooltipInfo("player", name, nil)

I get this error stack :

Message: Interface\AddOns\WeakAuras\WeakAuras.lua:4416: Usage: WeakAurasTooltip:SetUnitAura("unit", [index][, "filter"])

Locals: <none>

One other weird thing is that the function is not working if using spell ID instead of spell Name.

I'm sorry I got confused while reading index. I'm closing this issue.

To anyone reading this searching for an answer while stumbling on the same error :
The WeakAuras.GetAuraTooltipInfo function uses index instead of spellID or spellName. The index is the position of the aura you're looking for, meaning I ended up using this function to get the information from the tooltip :

function()
    local display = "amount"
    local name = GetSpellInfo(269279)
    local index = nil;
    
    -- Loop to get buff index
    for i=1,40 do
        local buff = UnitBuff("player", i)
        if buff == name then
            index = i
            break
        end
    end
    
    -- Set info as display text
    if name and index then
        local inline = select(3, WeakAuras.GetAuraTooltipInfo("player", index, HELPFUL))
        display = inline
    end
    
    return display
end
