attempt to index function with 'OnServerEvent' fix?

I am making a game where players can mine ores and gain money. I'm currently working on the mining part of the game. I have 2 events called Destroy (fired when a player finishes mining an ore) and Hit (fired when a player mines an ore). However, I've run into an error with the script that handles those 2 events. The error is "attempt to index function with 'OnServerEvent'" Here's the code:

local event = game.ReplicatedStorage.Events.Hit
local event2 = game.ReplicatedStorage.Events.Destroy

function frc(model)
	local children = model:GetChildren()
	local child = children[math.random(1, #children)]
	return child
end

event2.OnServerEvent:Connect(function(ore) --Error occurs here
	--ignore everything below this
	local pos
	local rot
	local hits = ore.Hits
	local newDecor
	
	if ore.Name == 'Ore' then
		newDecor = frc(game.ReplicatedStorage.DecorParts1):Clone()
	elseif ore.Name == 'Ore+' then
		newDecor = frc(game.ReplicatedStorage.DecorParts2):Clone()
	end
	
	if ore:FindFirstChild('Low') then
		pos = ore.Low.Position
		rot = ore.Low.Orientation
		ore.Low:Destroy()
	elseif ore:FindFirstChild('Medium') then
		pos = ore.Medium.Position
		rot = ore.Medium.Orientation
		ore.Medium:Destroy()
	elseif ore:FindFirstChild('High') then
		pos = ore.High.Position
		rot = ore.High.Orientation
		ore.High:Destroy()
	elseif ore:FindFirstChild('UltraHigh') then
		pos = ore.UltraHigh.Position
		rot = ore.UltraHigh.Orientation
		ore.UltraHigh:Destroy()
	end
	
	if newDecor.Name == 'Low' then
		ore.OreValue.Value = 5
		hits.Value = 3
		wait(30)
	elseif newDecor.Name == 'Medium' then
		ore.OreValue.Value = 15
		hits.Value = 6
		wait(60)
	elseif newDecor.Name == 'High' then
		ore.OreValue.Value = 35
		hits.Value = 10
		wait(180)
	elseif newDecor.Name == 'UltraHigh' then
		ore.OreValue.Value = 65
		hits.Value = 15
		wait(300)
	end
	
	newDecor.Parent = ore
	newDecor.Position = pos
	newDecor.Orientation = rot
end)

Please help! This script is critical to the game and I have no idea why the error is occurring. Thanks for taking time to look over my question.

I'm pretty sure that it's because your event is name destroy. I've encountered this problem myself and I had used a remote event name destroy.
