I use react-arcgis to create WebScene and append FeatureLayer into the scene map. And then tried to use saveAs function to save map including layers. However, an error message shows "FAILED TO SAVE WEBSCENE DUE TO UNSUPPORTED OR INVALID CONTENT. SEE 'DETAILS.ERRORS' FOR MORE DETAILED INFORMATION". When I didn't add future to the map, the saveAs function works. Are the feature layers the problem that causes the issue?
