@arcgis/core 4.21.2 error

Hi I am new to ESRI and the community, I am following the tutorial and trying to load a base-map (below example with @arcgis/core 4.21.2, linking the css directly from index.html), however, I am getting below error, anyone has an idea what went wrong or how to fix?

Cannot read properties of undefined (reading 'cssVarShim')

import Map from "@arcgis/core/Map"; import MapView from "@arcgis/core/views/MapView"; const map = new Map({ basemap: "dark-gray" }); const view = new MapView({ container: "viewDiv", map: map, zoom: 4, center: [-100, 40] });

Can you provide a sample app showing this issue? Not reproducible with the information given.

Thanks Rene, I switched to linking the CDN link directly and it seems ok, but I have another question, how do you determine when to use GraphicsLayers or GeoJsonLayer?
with 4.21.2 I ran into error like GraphicsLayers is not a constructor error
