At 160319: Error stopping an edit session with save edits—ArcGIS Pro | Documentation help is requested from anyone encountering that error.
While investigating LRS Line Networks I have stumbled across a procedure that leads to that error every time it is run a second time within an ArcGIS Pro 3.0.0 session.
The code is as below and the way I am running it is as a Python Script tool with no parameters.
If the tool is run once it works. If it is then run again it gives:
arcgisscripting.ExecuteError: ERROR 160319: Error stopping an edit session with save edits
Error stopping an edit session with save edits [TestLRSNetwork]
Failed to execute (AppendRoutes).
# This script is intended to create an empty LRS dataset and load
# the geometries of a test polyline feature class with route IDs (TEXT),
# Route Names (TEXT) and from/to measures (DOUBLE) into it so that an
# LRS Line Network with those routes can be created

If I close ArcGIS Pro and run the tool again, it will work, but if I try to run it a second time then it gives the error again.
