Declaration of a 2D Array

Hello there, I'm stuck trying to change some code. There was a declaration of a 2D array called drawPoints in a function which looked like this:

 void DrawOrbits () {
     CelestialBody[] bodies = FindObjectsOfType<CelestialBody> ();
     var virtualBodies = new VirtualBody[bodies.Length];
     var drawPoints = new Vector3[bodies.Length][];
     int referenceFrameIndex = 0;
     Vector3 referenceBodyInitialPosition = Vector3.zero;

     // Initialize virtual bodies (don't want to move the actual bodies)
     for (int i = 0; i < virtualBodies.Length; i++) {
         virtualBodies[i] = new VirtualBody (bodies[i]);
         drawPoints[i] = new Vector3[numSteps];
     }

I am trying to decompose the DrawOrbits() function in many functions, so I tried this in my class:

     public int numSteps = 1000;
     private CelestialBody[] bodies;
     private VirtualBody[] virtualBodies;
     private Vector3[][] drawPoints;
     private int referenceFrameIndex = 0;
     private Vector3 referenceBodyInitialPosition = Vector3.zero;
 
     void Start() {
         /* InitializeVirtualBodies() and drawPoints;*/
         bodies = FindObjectsOfType<CelestialBody>();
         virtualBodies = new VirtualBody[bodies.Length];
         for (int i = 0; i < virtualBodies.Length; i++) {
             virtualBodies[i] = new VirtualBody(bodies[i]);
             drawPoints[i] = new Vector3[numSteps];
 
             if (bodies[i] == centralBody && relativeToBody) {
                 referenceFrameIndex = i;
                 referenceBodyInitialPosition = virtualBodies[i].position;
             }
         }

And now I get this error: Assets\Scripts\Debug\OrbitDebugDisplay.cs(17,25): warning CS0649: Field 'OrbitDebugDisplay.drawPoints' is never assigned to, and will always have its default value null

I don't get how to declare drawPoints correctly, the code seems to take it like it was 2 differents variables.

Thanks for your help!
