Ent won't spawn?

So I am trying to spawn this ent but it won’t work.

Here is the error:


Attempted to create unknown entity type tdmcars_escalade!

[ERROR] gamemodes/sandbox/gamemode/init.lua:236: Tried to use a NULL entity!
  1. SetPos - [C]:-1
   2. unknown - gamemodes/sandbox/gamemode/init.lua:236
    3. unknown - lua/includes/modules/concommand.lua:69

I have the ent in my addons folder and in the gamemode/sandbox/entities/entities.

Any idea why i’m getting this error? Oh and here is the code:


concommand.Add( "spawnit",function( ply )
		
		local ent = ents.Create( 'tdmcars_escalade' )
		ent:SetPos( Vector( 826.474670, 500.543030, -79.968750 ) )
		ent:Spawn()
	
	end )
