[HELP] Why i cant get data from all accounts?

[Turbe$Z]

I want to get a data from all accounts on the server, but i get this warning:

'getAccount' [Expected string at argument 1, got account]
'getAccountData' [Expected account at argument 1, got boolean]

this is my code:

for i, v in pairs(getAccounts()) do 
	names = getAccountData(getAccount(v), "acc:nickname")
end 
	outputChatBox(names)

What wrong?

Well you have to do it like this

addCommandHandler('getdata',function(player,commandName)
    local playersData = {}
    local accounts = getAccounts()
    if player then 
            for k,account in ipairs(accounts) do 
            playersData[k] = getAccountData(account,"acc:nickname")
        end 
        outputChatBox(tostring(inspect(playersData)),player)
    end 
end,false,false)
