Node.js

Hello! hope you are doing well.
Im trying to update a database from nodejs.
But when i try to check it out on postman i got the error from the catch that i created.
Is it something that im doing wrong?.
The erro in the console is

Named parameter ":id" has no value in the given object.

What I have tried:

//PUT
server.put("/estudiantes/:id", async(req, res) => {
  const bodyParam = req.body;
  const idParam = req.params.id;
  try{
    const estudiantes = await db.query(`
    UPDATE estudiantes
SET :nombre :apellido :pais :edad
WHERE :id`,{
      replacements:{id: idParam.id,nombre:bodyParam.nombre,apellido:bodyParam.apellido,
        pais:bodyParam.pais,edad:bodyParam.edad},
          type: db.QueryTypes.UPDATE
        });
    res.status(200);
    res.json(bodyParam) 
  }catch (error){
    res.status(500);
    res.json({error:'Internal server error'})
    console.log(error.message);
  }

});
