I wonder if anyone has used the Python Caller transformer to create an ESRI feature layer using ArcPY or ArcRest to publish the feature layer in AGOL, Portal or ArcGIS server. I'd be interested to work together with anyone who has a use case for this. With Portal or AGOL writer I could create a feature service but I want my service to be rendered with the appropriate layer properties so all the user need to do is add the feature layer on a web map in Portal or AGOL. An appropriate SD file created from an MXD or lyr file would be necessary to store the layer properties.
Per FME documentation: AGOL writer layer creation is not supported.
