On premise we have the full stack of ArcGIS at 10.3.1: AGS, Portal, ArcGIS Data Store. The ArcGIS Data Store is an out-of-the-box configuration. The PostgreSQL geodatabase backend is used. I had my DevOps install and configure the ArcGIS Data Store for my hosted services (feature layers and Survey123).
Following the instructions for publishing a hosted feature service here: https://blogs.esri.com/esri/arcgis/2015/02/18/related-tables-exploring-new-ways-to-use-collector-for-arcgis/ (in fact, using the sample data from HydrantInspections!)
I have enabled the feature service for offline use. GlobalID are there, etc. offline is enable in Portal, etc.
In Collector I attempt to download the map and get the error below.
I've looked in the AGS Server directories and do see the HydrantInspections.mxd and HydrantInspections.msd, so apparently those directories are visible when the feature service is created. However it appears that the path to the msd is not visible to the "Create Feature Service Replica" process.
So... Can anybody give me a hand with this?
