Why is this DataStore ban script throwing an error?

I am experimenting with a simple ban system. I am trying to save the admin name and a true/false value that says whether the player is banned or not. To do this, I am saving a table and it is not going so well. It throws this error when I try to index plrdata: ServerScriptService.BanWatch:12: attempt to index local 'plrdata' (a boolean value). I am not sure why it is doing this.

Script that watches for banned players to join:

local localdata = game:GetService("DataStoreService"):GetDataStore("bans")


game.Players.PlayerAdded:Connect(function(plr)
    local plrdata
    pcall(function()
        plrdata = localdata:GetAsync(plr.UserId.."-ban")
    end)

    if plrdata ~= nil then

        if plrdata['bankey'] == true then
            plr:Kick("You have been banned by the admin "..plrdata[1]..", you may appeal if eligible.")
        end

    else

        local banInfo = {"none", false}

        localdata:SetAsync(plr.UserId.."-ban", banInfo)
    end
end)

Script that sets the table:

game.ReplicatedStorage.RemoteEvents.Ban.OnServerEvent:Connect(function(plr, userid)

    local banInfo = {plr.Name, ['bankey'] = true}

    game:GetService("DataStoreService"):GetDataStore("bans"):SetAsync(userid.."-ban", banInfo)


    if game.Players:GetPlayerByUserId(userid) then
        game.Players:GetPlayerByUserId(userid):Kick("You have been banned by the admin "..plr.Name..".")
    end
end)
