Newly added SharePoint List column is hidden - SPFx WebPart

Question

I added list column as below using pnp js and api call is working without issue. but Column is hidden even it is created.
is there any reason for that ?

var fieldXML = "<Field Hidden='FALSE' DisplayName='455' Format='Dropdown' IsModern='TRUE' MaxLength='255' Name='455' Title='455' Type='Text'><Default>11</Default></Field>";  

      sp.web.lists.getByTitle("listTitle").fields.createFieldAsXml(fieldXML).then(function (result) {
       //success  
      });

If you are scanning a nested array, here's one way to about that using includes to check the actors array.

const moviesList = [{
    "movieId": 4192148,
    "title": "Highly Functional",
    "actors": [
      3188187,
      3306943,
      132257,
      47265
    ]
  },
  {
    "movieId": 11111,
    "title": "Highly Functional2",
    "actors": [
      3188187,
      3306943,
      206,
      47265
    ]
  },
  {
    "movieId": 11112,
    "title": "Highly Functional3",
    "actors": [
      3188187,
      3306943,
      206,
      47265
    ]
  }
];

let matches = [];
for (const movie of moviesList) {
  const { actors, movieId } = movie;
  if (actors.includes(206)) {
    matches.push(movieId);
  }
}

console.log(matches);

// Another format

matches = moviesList
  .filter(({ actors }) => actors.includes(206))
  .map(({ movieId }) => movieId)
  
  
console.log(matches);
