Hello,
I'm getting this error when trying to export a subnetwork from the ArcGIS API for Python.
A subnetwork controller cannot be purged before disabled.
It only occurs for one specific subnetwork that behaves normally in ArcGIS Pro (not dirty, can be modified and validated...)
Exporting this subnetwork is working as expected when done in ArcGIS Pro with the toolbox, with arcpy.un.ExportSubnetwork and even in the REST API.
Any idea ?
