  exports.deletePet = (req, res) => {


    Pet.findByIdAndDelete(req.params.id)
     .then((pet) => {
       if (!pet) {
         res.status(400).send({
             status: ' not found'
         });
       } else {
         res.status(200).send({
             status: "succes"
         });
       }
     })
     .catch((err) => {
       console.error(err);
       res.status(500).send('Error: ' + err);
     });

  };

what i expect :

{ status: “succes” }
