How would I get the children of a GoogleSpreadsheet?

So, I’m currently trying to make a discord bot database that can ban people with a reason in my roblox game.

Everything works, but I just can’t seem to get another column. Which is the “reason” for ban.

I’ve tried to get all the data in the google spreadsheet, but it just keep saying an error.

ServerScript Code (Location: game.ServerScriptService):

for _,player in pairs(game.Players:GetChildren()) do
        local ReValue = globalDatabaseGlobal:GetAsync(player.UserId)
        local banTable = ReValue:GetAsync(player.UserId.."reason")
local reason = banTable[1]
        if ReValue == true then
            player:Kick("You've been banned by Console. Reason: "..reason[1]) 
        end
    end

ModuleScript Code (Location: game.ServerScriptService.ServerScript):

local Global = --// MADE EMPTY FOR PRIVACY REASONS
local URL = "https://script.google.com/macros/s/" .. Global .. "/exec"
local httpService = game:GetService("HttpService")
local module = {}
game:WaitForChild("NetworkServer")
function decodeJson(JSON)
  local jsonTab = {}
  pcall(function()
  jsonTab = httpService:JSONDecode(JSON)
  end)
  return jsonTab
end
function encodeJson(data)
  local jsonString = data
  pcall(function()
  jsonString = httpService:JSONEncode(data)
  end)
  return jsonString
end
function doGet(GoogleSheet, KeyID, reason)
    local JSON = httpService:GetAsync(URL .. "?sheet=" .. GoogleSheet .. "&key=" .. KeyID)
    local data = decodeJson(JSON)
    print(JSON)


  if data.result == "success" then
    return data.value
  else
    return
  end
end
function doPost(GoogleSheet, KeyID, data)
  local JSON = httpService:UrlEncode(encodeJson(data))
  local RTJSON = httpService:PostAsync(URL, "sheet=" .. GoogleSheet .. "&key=" .. KeyID .. "&value=" .. JSON, 2)

  local data = decodeJson(RTJSON)
  if data.result == "success" then
    return true
  else
    return false
  end
end
function module:GetDatabase(GoogleSheet)
  local database = {}
  function database:PostAsync(KeyID, value)
    return doPost(GoogleSheet, KeyID, value)
  end
  function database:GetAsync(KeyID)
    return doGet(GoogleSheet, KeyID)
  end
  return database
end
return module

(ps I am not good with HTTP stuff. Any help would be appreciated!)
