I'm trying to execute a Data Interoperability tool I've created for publishing it on an ArcGIS Server. I'm on 10.3.1.
The tool is inside a custom toolbox and works perfectly if I run it in edit mode. However, if I try to execute it directly from ArcMap, I obtain the following:
ERROR 000819: The tool is not assigned.
Failed to execute ().
Can't figure out why, hope someone can help!
