LocalizationService help

tl;dr: LocalizationService isn’t translating correctly?

This is a snippet of a function in a module.

function LocalizationModule:TranslateStringAsync(...) --/ (player), string, (pathway), (LocaleId) / if this is being called from the client the player agrument doesn't need to be supplied

    local Args = {...}
    local Player
    local String
    local Pathway
    local LocaleId
    if CheckEnvironment.IsServer == true then
        Player = Args[1]
        String = Args[2]
        Pathway = Args[3]
        LocaleId = Args[4]
    elseif CheckEnvironment.IsClient == true then
        Player = Players.LocalPlayer
        String = Args[1]
        Pathway = Args[2]
        LocaleId = Args[3]
    else
        error('Script environment is not valid for translation!', math.huge)
    end

    if not Pathway then Pathway = game end

    if LocaleId then
        print(LocaleId)
        local GetTranslator do
            function GetTranslator()
                local success, translator
                for retries = 1, MaxRetriesForAsynchronousCall do
                    success, translator = pcall(function()
                        return LocalizationService:GetTranslatorForLocaleAsync(LocaleId)
                    end)
                    if success then
                        break
                    end
                    RunService.Stepped:Wait()
                end
                return {success, translator}
            end
        end
        
        local TranslatorObject = assert(GetTranslator()) --/* TODO: remove assert (?)
        local Success = TranslatorObject[1]
        local Translator = TranslatorObject[2]
        if Success then
            return Translator:Translate(Pathway, String)
        else
            warn('After ' ..MaxRetriesForAsynchronousCall.. 'retries the translator still failed to fetch, not going to translate content.', debug.traceback()) return
        end
        
    end

I’m calling it from the client and everything is working as expected. I am supplying a manual locale Id for testing to see if it will properly translate. Here is the call from the client:
print(Localization:TranslateStringAsync('Hello, how are you?', nil, 'fr'))
It works as expected and returns, but the output isn’t translated at all. What’s wrong here? Is LocalizationService unfinished? It says French is currently supported.

Output:

 fr
 Hello, how are you?

This may seem as a little late, but this is what I am getting too. Everything gets printed properly except for the actual translation which doesn’t work at all. It just outputs the original message.

Would be great if somebody actually replied on this issue, as this is yet to be resolved 4 years later, despite seemingly doing everything else correctly.
