Getting [object, Object] when printing JSON object from req.body to the console

Question

I'm trying to add a product's detail into my API's PostgreSQL database using Postman but when I print the values of the specs key to the console, I get [object Object] instead of the whole data, so even in my PostgreSQL jsonb column the data is stored as [object, Object].

const createProduct = async (req, res, next) => {
  const { name, description, quantity, price, img_url, specs } = req.body;
  
  // Results in [object Object]
  console.log(specs);

  try {
    await db.query(insertProduct, [
      name,
      description,
      quantity,
      price,
      img_url,
      specs,
    ]);

    res.status(201).json({ message: "Product Added Successfully" });
  } catch (err) {
    console.error(err);
    next(err);
  }
};

This is the json object that is being added in Postman:

{
    "name": "Samsung GALAXY Note II",
    "description": "Samsung Galaxy Note II sports a slightly bigger, 5.5-inch display, a quad-core processor that gets rid of the slight lag in the original Note, and best of all Android 4.1 Jelly Bean right out of the box.",
    "quantity": 10,
    "price": 249.99,
    "img_url": "www.google.com/sexyjutso",
    "specs": {
        "display": [
            {
                "size": "5.5",
                "resolution": "1280 x 720"
            }
        ],
        "camera": [
            {
                "photo": "8 MP",
                "video": "1080p"
            }
        ],
        "hardware": [
            {
                "ram": "2GB",
                "chipset": "Exynos 4412 Quad"
            }
        ],
        "battery": "3100mAh",
        "colors": [
            "Titanium Gray",
            "Marble White",
            "Amber Brown"
        ]
    }
}

I even tried stringifying the specs but that too returns [object, Object].

Is there any way to fix this?

Answer 1

I was using express-validator and that was sanitizing the specs by trimming and escaping its values and completely messing up the JSON object.

Removing that part fixed the frustrating problem.
