			StartRay.Parent = game.Workspace.TempEffects
			EndRay.Parent = game.Workspace.TempEffects
			MirrorSend.Parent = game.Workspace.TempEffects
			
			local Filter = game.Players:GetChildren()
			local RayCastWhiteList = RaycastParams.new
			
			RayCastWhiteList.FilterDescendantsInstances{StartRay{}
			RayCastWhiteList.FilterType = Enum.RaycastFilterType.Whitelist
			
			
			while wait() do
				local result = workspace:Raycast(StartRay.Position, EndRay.Position -StartRay.Position, RayCastWhiteList)
				print(result)
			end

No matter what I try to whitelist or blacklist, even if a single part, I get the same error.

ServerScriptService.MirrorManSend:33: attempt to call a table value - Server - MirrorManSend:33
I really have no idea why, please help.

Could you please use the lua format, or at least show us what is on line 33 in the image?

The error is happening because you’re using {} brackets rather than (). The line should look like such:

RayCastWhiteList.FilterDescendantsInstances = {StartRay}

Edit: yeah connect pointed out the mistake lmfao mb, fixed it

RayCastWhiteList.FilterDescendantsInstances = {StartRay}
it should be

also use task.wait(), would be more consistent for your user case
