I am writing a print service for client that does not have ArcServer because they are small and are using only ArcGIS Online as their mapping platform. Since I cannot use the ArcServer print services, I've utilized the python api in a django app to generate the map print and return the document to browser. It works well in web app builder, but when I download the app to IIS and hook it up with the proxy, the Export Map Task returns errors that it is unable to create layers. The error is basically identical to the issue when using the Print Service in the jsapi on a web map running through the proxy. Is the proxy still going to cause an issue with creating the print even though the python api is using the GIS object with credentials to run the Export Map Task? My other option is to use ArcPro python library and export the map, but will the proxy still cause issues? If so, what can I do? Our client really needs to print and we want their organization to fall in love with esri.
