You are close. You should push to comments field, and you specified comment. Just refactor your code like this:

.post(function(req, res){
  let bookid = req.params.id;
  let comment = req.body.comment;
    
  Book.findOneAndUpdate({_id:bookid},
    { $push:{comments: comment} },
    { $inc:{commentcount: 1} 
  }).then(data=>res.json(data))
});

Here is the working example: https://mongoplayground.net/p/J0DeY2IB6WF
