I get this exception when I perform a raycast:

Exception

Do I need to add some dependency to my job?

I have made a simplified version:

public class EnemySystem : SystemBase
{
        private PhysicsWorld _PhysicsWorld;

        private Random random = new Random(22);

        protected override void OnCreate()
        {
            base.OnCreate();
            _PhysicsWorld = World.DefaultGameObjectInjectionWorld.GetExistingSystem<BuildPhysicsWorld>().PhysicsWorld;
        }

        protected override void OnUpdate()
        {
            var rayCaster = new MovementRayCast
            {
                PhysicsWorld = _PhysicsWorld
            };
            random.NextInt();
            var rand = random;
            var frame = UnityEngine.Time.frameCount;
            Entities.ForEach((ref Movable movable, ref Enemy enemy, in Translation translation) =>
            {
                var ray = new RaycastInput
                {
                    Start = translation.Value,
                    End = translation.Value + movable.direction * 0.9f,
                    Filter = CollisionFilter.Default
                    /*new CollisionFilter
                    {
                        GroupIndex = 0,
                        BelongsTo = 1u << 1,
                        CollidesWith = 1u << 2
                    }*/
                };
                Debug.Log($"WallAhead {rayCaster.PhysicsWorld.CastRay(ray)}");
           }).WithoutBurst().Run();
        }

    private struct MovementRayCast
    {
        [ReadOnly] public PhysicsWorld PhysicsWorld;
    }
 }

I have found an issue can be closed.
