Problem on peripheral.find

Hey guys the code is this:

capa = peripheral.find("tile_blockcapacitorbank_name")
reactor = peripheral.find("BigReactors-Reactor")

-- Num of capacitors
local maxCapacitor = 15
-- Max energy stored by Capacitors
local maxEnergy = capa.getMaxEnergyStored() * maxCapacitor

-- Turn on at
local turnOnAt = 50
-- Turn off at (Not use 100)
local turnOffAt = 90

local manual = false

while true do
  energyStored = capa.getEnergyStored() * maxCapacitor
  energyPerc = math.floor((energyStored / maxEnergy) * 100)
  print(energyPerc)
  if energyPerc <= turnOnAt then
    reactor.setActive(true)
    print("Activating the reactor")
  elseif energyPerc >= turnOffAt then
    if reactor.getActive() then   
	  print("Deactivating the reactor")
	  reactor.setActive(false)
    end
  end
  sleep(10)
end

It was working properly whitout any problem, until by mistake I did destroy the Capacitor modem that is attached to the openperipheral, so the name did go from "tile_blockcapacitorbank_name_0" to "tile_blockcapacitorbank_name_1" now I get an error every time on the line 7 ?!

Rly don't understand the problem here :/

And the error is…?

Double check that you correctly reconnected the cabling between the computer and the capacitor.

the modem on the capacitor should have a red ring square light
