Tried. It can't create filestream

bankAccounts folder exists. Just it can't make a filestream. Error is: error to get global fil (got a nil).

When I try to switch from wb to w. Nothing happens. Same error.

With events anything is okay. Error appears when computer got a message and tries to make changes to file system.

I want to make my bank system for my server, but I got problem when making bank network.

When server tries write a file, it got an error like fil = nil. I can't solve the problem, so please help me!

There's the code:

local com = require("component")
local ev = require("event")
local fs = require("filesystem")
local net = com.modem
net.open(15)
print("Opened Net. Waiting for commands")
while true do
  local _,_,from,port,_,message,nick,balance = ev.pull("modem_message")
  if message == "getInfo" then
    if fs.exists("bankAccounts/"..nick) then
      local fil = io.open("bankAccounts/"..nick,"r")
      bal = fil:read(1000)
      fil:close()
      net.send(from,15,nick,bal)
    else
      net.send(from,15,"no info")
    end
  end
  if message == "setInfo" then
    local fil = io.open("bankAccounts/"..nick,"wb")
    fil:write(balance)
    fil:close()
    net.send(from,15,"done it")
  end
end
