I would like to include custom text elements in my layouts for ArcGIS Online WAB Print Widget. As our Server is on 10.3 and does not include the Get Layout Templates Info Task by default, I followed this blog:
and used the python script from Github https://github.com/arcpy/sample-gp-tools/tree/master/GetLayoutTemplatesInfo
Both the export webmap and the Get Layout Templates Info task run and publish successfully fololwing the help http://server.arcgis.com/en/server/10.4/get-started/windows/tutorial-publishing-additional-services-for-printing.htm and the Get Layout Info shows my custom text elements (see attached).
Nevertheless, when I include my ExportWebmap Task in ArcGIS Online I can print, but the Custom Text Elements are not shown in the advanced tab.
There are no error messages and I have no idea where to start looking for a reason why this is not working.
Any help would be greatly appreciated!
