I would like to add a web map from my organization's Portal to a Story Map served on a separate server (still within our network).
Is this a valid (supported) configuration?
Web map and it's layers are shared with everyone and I'm able to pass the web map's ID successfully. But, the web map won't render in the Story Map app - it's looking for siblings of the mapContainer which is undefined.
This is where it fails (Dev tools debugging):
this.getMapConfig = function(response, mapContainer) ... legend: new Legend( response, app.isInBuilder, getLegendSettings( mapContainer, response.itemInfo.item.id) ), ...
object is populated, so it seems like the web map is being accessed.
