delete object not working

// define dis-allowed keys and values
const disAllowedKeys = ['_id','__v','password'];
const disAllowedValues = [null, undefined, ''];

// our object, maybe a Mongoose model, or some API response
const someObject = {
  _id: 132456789,
  password: '$1$O3JMY.Tw$AdLnLjQ/5jXF9.MTp3gHv/',
  name: 'John Edward',
  age: 29,
  favoriteFood: null
}; 

// use reduce to create a new object with everything EXCEPT our dis-allowed keys and values!
const withOnlyGoodValues = Object.entries(someObject).reduce((ourNewObject, pair) => {
  const key = pair[0];
  const value = pair[1]; 
  if (
    disAllowedKeys.includes(key) === false &&
    disAllowedValues.includes(value) === false
  ){
    ourNewObject[key] = value; 
  }
  return ourNewObject; 
}, {}); 

// what we get back...
// {
//   name: 'John Edward',
//   age: 29
// }

// do something with the new object!
server.sendToClient(withOnlyGoodValues);
