I am trying to share a feature class from gdb as web layer by using ArcGIS Pro 2.0.0 and portal for ArcGISÂ and I found the error (00134: Layer's data source is not supported) but when I am using .sde database the sharing process working well after I import the database to federated ArcGIS server.
Please see the screenshot below

Is it possible to share the gdb data As web layer to ArcGIS portal?
