I am trying to publish hosted feature layer on recently upgraded portal 10.6 (from 10.4) and am getting below error .
I have published both from ArcMap and also portal add item feature. No issue with the data or MXD .
To give you an background, our enterprise stack was upgraded recently - all components were upgraded successfully except data store. Later we have to re-install and install 10.6. Data store is validating fine . But we could not publish hosted layers, normal map service publishing is good.
Checked portal logs, server logs etc .. but no clue. Permissions are intact in all folders (arcgisportal, ArcGIS) etc.
This seems mystery , any pointers would be highly appreciated.
