I'm receiving two errors (below) that need resolution before I will be able to share a map I've created to ArcGIS Online (from ArcGIS Pro's interface). The map document was originally created in ArcMap 10.5(?) and then imported into Pro. I'm using the Canada Lambert Conformal Conic projection with the input layer.
I can't for the life of me seem to get past either. I've added a few different base maps but that just yields a different error.
Some fresh insight would be very much appreciated.
