I am trying to add an annotation layer to a JS application, with URLs structured similar to Layer: ROW Dimensions (ID: 0)
and Layer: ROWDimension (ID: 1) . When I add them as a feature layer, only a black box appears. (I think I am doing this wrong with sublayers or something...) When I add them as a Map Image Layer, I get a CORS error. What is the best way to add these to get the text into the application?
