ActivateCameraController did not select a module. - Client - CameraModule:335

So I was making the player’s camera look toward an NPC whenever they get close to it for a custom NPC dialogue system, but then I got this error:

  ActivateCameraController did not select a module.  -  Client - CameraModule:335

what does this mean? My script is the following:

local player = game.Players.LocalPlayer
local MAX_RANGE = 15

while true do
	while player:DistanceFromCharacter(workspace.Dummy.Head.Position) < MAX_RANGE do
		local camera = game.Workspace.CurrentCamera
		camera.CameraType = "Scriptable"
		camera:Interpolate(game.Workspace.LookFromPart.CFrame,game.Workspace.Dummy.Torso.CFrame,1)
		return 
	end
	wait()
end

you enter the camera type as a string
try Enum.CameraType.Scriptable
