Can't create new Polyline

[Zoggo]

I can't create a new Polyline Geomtery Object in Experience Builder 1.5. If I use the code

new polyline({..})

my widget will not be loaded any more (fail to load):

import Polyline from 'esri/geometry/Polyline';

zoomTo = (geom: IGeometry) => {
    if (this.jimuMapView) {
      const pl = new Polyline({
        paths: (geom as IPolyline).paths,
        spatialReference: geom.spatialReference
        
      });
      this.jimuMapView.view.goTo(pl).catch(function (error) {
        if (error.name != "AbortError") {
          console.error(error);
        }
      });
    }
  }

It seems to be a Import problem. if I use 

import Polyline from 'esri/geometry/Polyline';

the widget can't load when I use new Polygon({..}).

if I use use

constructor(props) {
    super(props);
    loadArcGISJSAPIModules([
      "esri/geometry/geometryEngine",
      "esri/geometry/Polyline"
    ]).then((modules) => {
      [this.geometryEngine, this.polyline] = modules;
      console.log("ESRI API Moduls loaded");
    });
  }

I can use the Polygon type like this

zoomTo = (geom: IGeometry) => {
    if (this.jimuMapView) {
      const pl = new this.polyline({
        paths: (geom as IPolyline).paths,
        spatialReference: geom.spatialReference
        
      });
      this.jimuMapView.view.goTo(pl).catch(function (error) {
        if (error.name != "AbortError") {
          console.error(error);
        }
      });
    }
  }

But I don't understand why I can't use import?

This is the solution: 

Try adding this to your manifest.json:

 "dependency": [
    "jimu-arcgis"
  ]
