Raycast to point don't work

Questions

Hello.
I try to check if something is between camera and position in scene. I use raycast but it doesn’t work, it only hits the object from a certain camera position.

      const startPosition = this.camera.position;
       let direction = new THREE.Vector3();
       direction.subVectors( startPosition, positionTarget ) ;
       const distance = startPosition.distanceTo(positionTarget);
       const raycast = new THREE.Raycaster(startPosition,direction.normalize(), 0, distance );
       
       const intersects = raycast.intersectObjects(this.sceneMeshes);
       for (let i = 0; i < intersects.length; i++)
       {
           console.log(intersects[0].object.name, intersects[0].point)
       }

When i use raycaster to from camera then it hit everything on scene properly. How should I check if there are obstacles between two points?

I had wrong direction.
Fix:

 direction.subVectors( positionTarget , startPosition) ;
