updateOne does not update multiple fields and does not create new fields in a record

April 18, 2022

I am using NodeJs and MongoDB atlas for saving/updating user profiles. However, the updateOne method does not update multiple fields and I do not know why! It only works for one variable and not for the whole record! Here is my code:

app.post("/edit-profile", async (req, res) => {
  if(req.body.password || req.body.phoneNumber){
    res.status(401);
    res.send({"error": "this api is not for changing password or phoneNumber"})
  } else {
    console.log("let's update this user: id="+req.body.id)
    console.log(req.body)
    result = User.updateOne(
      { _id: ObjectId(req.body.id)},
      req.body,
      (error, result) => {
        if (error) {
          console.log(error);
          res.status(400);
          res.send();
        } else {
          if (result.n > 0) {
            console.log("result")
            console.log(result)
            res.header({ sessionToken: "testToken" });
            res.send(req.body);
          } else {
            console.log("there is no user with this id")
            res.status(404);
            res.send({"message":"There is no user with this id!"});
          }
        }
      }
    );
  }
});

for example whenever, when I have it works for

{
    "id":"6253024ca9a2fb3a9a8d3675",
    "weight":888
}

but does not work for

{
    "id":"6253024ca9a2fb3a9a8d3675",
    "height":999
}

only works for weight parameter and does not create a new field (height). Even I used multiple fields at the same time and got the same results.
Also, I have another API for updating the meals item and it has a similar structure and it works. Here is my code for this API:

app.post("/edit-meals", async (req, res) => {
  const { error } = mealSchema.validate(req.body);
  if (error) {
    res.status(400); // 400 bad request
    res.send(error.details[0].message);
  } else {
    const meal = await Meal.findOne({ title: req.body.title });
    if (meal) {
      Meal.updateOne({ title: req.body.title }, req.body, (err, result) => {
        if (err) {
          res.status(403);
          res.send;
        } else {
          res.send(req.body);
        }
      });
    } else {
      res.status(404);
      res.send();
    }
  }
});

Although the updateOne works in the edit meals but it does not work in edit user. I would be grateful if anybody could help me through this.
