I have tried adding document using mongoose. The following code in productController.js, returns the following response.
Code:

exports.createProduct = async (req, res, next) => {
  try {
    console.log("Request Body:", req.body); // Log the request body for debugging
    const product = await Product.create(req.body);

    res.status(201).json({
      success: true,
      product,
    });
  } catch (error) {
    console.error("Error creating product:", error);
    res.status(400).json({
      success: false,
      message: error.message,
    });
  }
};

Response:
Request Body: {
name: ‘Vaseline petrolatum Jelly’,
description: ‘Simple product.’,
price: 100,
rating: 3,
category: ‘Health’,
images: { public_id: ‘sample public id’, url: ‘sample url’ }
}
but I cannot seem to find it in compass.

I have checked the DB_URL etc. and checked to see if there are any faults but there do not seem to be any.
