Toqure won't register my Debris object...

So I defined a debris datablock like so

ParticleTest.cs

datablock DebrisData(ParticleTest)
{
   render2D = true;
   texture = "~/data/particles/shiny2.bmp";
   elasticity = 0.5;
   numBounces = 5;
   bounceVariance = 2;
   friction = 0;
   velocity = 20.0;
   velocityVariance = 0.5;
   terminalVelocity = 30;
   gravModifier = -1.0;
   lifetime = 240.0;
   lifetimeVariance = 0;
};

In my server's game.cs I did the following

game.cs

exec("~/data/shapes/particles/ParticleTest.cs");

...

function GameConnection::createPlayer(%this, %spawnPoint)
{
    .....

   // Give the client control of the player
   %this.player = %player;
   %this.setControlObject(%player);
   
   
   %particle = new Debris()
   {
      dataBlock = ParticleTest;
      position = "1 1 1";
   };
   
   %particle.position = %player.getPosition();
}

When the code gets executed, Torque gives me the following error...

"Register object failed for object (null) of class Debris."

What more do I need to do to register the object? Thanks!
