Reactjs – Why is it returning addresses as null?

Address Function :-

export const GetAddress = async (req, res) => {
  let user = req.user;
  try {
    if (!user) {
      res.status(404).json({ message: "User not Found", success: false });
      return;
    }

    let id = await user.address[0];
    console.log(id);
    let addresses = await Address.findById(id);
    console.log(user);
    if (!addresses) {
      res.status(404).json({
        message: "No Address Found",
        success: false,
      });
      return;
    }

    res.status(200).json({
      message: `Welcome Back`,
      addresses,
      success: true,
    });
  } catch (error) {
    console.log(error);
    ErrorHandler(res, error);
  }
};

UserData :-

{
  _id: new ObjectId('657be59e80baafa1288a5169'),
  firstName: '***',
  lastName: '**',
  email: '*******@gmail.com',
  password: '$2a$10$cfJUXElsffQaM6T0QCA03O5XomIyVhLgALE3auxQzkpgCysJLY0Ei',
  address: [
    new ObjectId('657da734d4f75aa0f22a051e'),
    new ObjectId('657da86fd4f75aa0f22a053a'),
    new ObjectId('657da8e0d4f75aa0f22a054e'),
    new ObjectId('657da9fbd4f75aa0f22a0552'),
    new ObjectId('657daa22d4f75aa0f22a0556')
  ],
  cart: [],
  __v: 0
}

Now as you can see I already have addresses in user’s profile even after that if I try fetch a address using the address function it still throws the error

    1. Is mongoose installed and imported?
    2. In this line you’re drawing data from req object (not from mongoose) so using ‘await’ isn’t neccessary:
    let id = user.address[0];

    in this line it is neccessary:

    let addresses = await Address.findById(id);
    1. Most likely that instead of req.user you should access req.body.user

    But – what is the object you sent into the request named – User or UserData?

    1. Have you tried to refer to object id as mongoose.Types.ObjectId?

    about mongoose objectId:
    Output for ObjectId is a complex type (that contains value-kay pairs).

    When inserting to db – the expected type should be <mongoose.Schema.Types.ObjectId> and then no conversion is needed.
    Trying to read or compare ObjectId – adding .toHexString() is needed (because its a complex type) <User.address[0].toHexString()>

    1. When printing it, it should be one of these two options:
    console.log(id.toHexString());

console.log(req.body.user.address[0].toHexString());

    You should convert ObjectId to string.

    let id = await user.address[0]; // The type of id is ObjectId.
console.log(id);
let addresses = await Address.findById(id.toString()); // Convert ObjectId to string
