Default environment variables set in an ArcGIS Pro 2.4 Python script are incorrectly inherited when published to ArcGIS Server 10.7.

Solución alternativa

Manually delete the addition line:

arcpy.env.workspace = arcpy.arcpy.env.packageWorkspacepy.env.packageWorkspace.scratchGDB

Publish the following simplified script to ArcGIS Server after registering a folder with server:

import arcpy

arcpy.env.workspace = r'C:\Users\<username>\Documents\ArcGIS\Projects\PythonWorkspace'

scratchWorkspace = arcpy.env.scratchGDB

arcpy.AddMessage(arcpy.env.workspace)

ArcGIS Server changed this to:

import arcpy

arcpy.env.workspace = arcpy.env.packageWorkspace

scratchWorkspace = arcpy.env.scratchGDB

arcpy.AddMessage(arcpy.env.workspace)

This script does run.
