What am I doing wrong with the Collider2D.Cast function?

I have this code:

1 var hitResults = new RaycastHit2D[10];

2 var hitX = collider.Cast(new Vector2(desiredX, 0), bodyFilter, hitResults);

3 //var test = new Collider2D[10];

4 //hitX = collider.OverlapCollider(bodyFilter, test);

5 if (hitX == 0)

6 {

7 transform.Translate(desiredX, 0, 0);

8 }

The bodyFilter is a ContactFilter2D.

When I run the code like this, the character ignores all collisions with walls. When I uncomment line 4 and 5, the character stops moving horizontally once it is colliding with a wall.

What's wrong about my call to the Collider2D.Cast function?
