This behavior is expected. This is creating lines using latitude and longitude coordinates (WGS 84) but displaying them on a Web Mercator map. In this setup, the feature layer’s spatial reference is WGS 84, while the map uses Web Mercator. When the JavaScript API reprojects the feature tile extents from Web Mercator (102100) to WGS 84 (4326), the reprojected extents no longer overlap the lines.
Because of this, the lines are not displayed at all.
This can be resolved by:
- Setting the layer’s spatial reference to match the map view.
- Using geometries in the same spatial reference as the map view.
- Densifying the geometry (adding more points) so it correctly intersects the visible area.
Option 1 is most straightforward in this case and here is the codepen updated - https://codepen.io/U_B_U/pen/LEGoxzX?editors=1000.
