Why cant I delete an item in an object using `delete`

  static profile = async (req: Request, res: Response) => {
    try {
      const { username } = req.params;
      const account = await userModel
        .findOne({ 'shared.username': username })
        .exec();
      if (account) {
        delete account.shared.email; // <======= Why isnt this deleteing email
        console.log(account.shared);
        res
          .status(200)
          .send({ shared: account.shared, lastSeen: account.updatedAt });
      } else res.status(400).send({ message: 'Server Error' });
    } catch (error) {
      res.status(400).send({ message: 'Server Error', error });
    }
  };

console.log(account.shared) shows the below

{ language: 'en',
  loggedIn: true,
  warningMessage: 'verify',
  username: 'bill',
  email: '[email protected]',   // <===== Why is this still here?
  fullName: 'Bill',
  location: '/contact',
  gender: 'male',
  avatarId: '338fcdd84627317fa66aa6738346232781fd3c4b.jpg',
  country: 'US' }

if id do

console.log(account.shared.email); // undefined

I get undefined but if I console.log(response) on the front end the email is still in the object

You declared const account, might be that declaring account as a constant prevents the delete to alter the object. Try using var account instead.

You can omit it using ES6 syntax like this

if (account) {
        const {email, ...otherFields} = account.shared;
        console.log(otherFields);
        res
          .status(200)
          .send({ shared: otherFields, lastSeen: account.updatedAt });
      } else res.status(400).send({ message: 'Server Error' });
    }
