Hello, if somebody worked with google earth engine API into Angular please help me. I receive this error when I try to initialize library: Cannot use 'in' operator to search for 'Filter' in undefined

This is code:

 public googleEarthEngine() {
    // Load client library.
const ee = require('@google/earthengine');

  // Initialize client library.
  const initialize = function () {
    ee.initialize(null, null, () => {
      createMap();
    }, (e) => {
      console.error('Initialization error: ' + e);
    });
  };

  // Authenticate using an OAuth pop-up.
  ee.data.authenticateViaOauth('my code', initialize, (e) => {
    console.error('Authentication error: ' + e);
  }, null, () => {
    ee.data.authenticateViaPopup(initialize);
  });


function createMap() {
  // Initialize map.
  const mapEl = document.querySelector('#earthmap');
  const map = new google.maps.Map(mapEl, {
    center: new google.maps.LatLng(39.8282, -98.5795),
    zoom: 5
  });

  // Load EE image.
  const image = ee.Image('srtm90_v4');
  image.getMap({ min: 0, max: 1000 }, ({ mapid, token }) => {

    // Create Google Maps overlay.
    const mapType = new google.maps.ImageMapType({
      getTileUrl: ({ x, y }, z) =>
        `https://earthengine.googleapis.com/map/${mapid}/${z}/${x}/${y}?token=${token}`,
      tileSize: new google.maps.Size(256, 256)
    });

    // Add the EE layer to the map.
    map.overlayMapTypes.push(mapType);

  });
}
}

I seeing a very similar issue, also trying the initialize(), however the error message is slightly different:

TypeError: Cannot use 'in' operator to search for 'Classifier' in undefined
