Physics Raycast

Hi recently I made a grappling game where player had to grapple on to cubes and complete the level. There i used raycasting but now I'm able to raycast into air and grapple into air any ideas how to fix it Please Help

You can check if the ray hit the certain tagged object like

RaycastHit hit;
If(Physics.Raycast(origin,direction,out hit,max distance)){
   If(hit.tag == "cube"){
      //grapple 
   }
}
