Why cant i use fire server from local script in player scripts?

I have this script

--local script-
local UserInputService = game:GetService("UserInputService")

function onKeyPress(inputObject, gameProcessed)
	if inputObject.KeyCode == Enum.KeyCode.E then
	game.ReplicatedFirst.Button1:FireServer()	
	end
	end



UserInputService.InputBegan:Connect(onKeyPress)

i have tested this with a print statement inside the if statement on line 5 so it is a correct statement but its not firing the event this is the script in the event

--script--
script.Parent.OnServerEvent:Connect(function()
print("e")
end)
