Hi all,
This post is a workaround for people who receives the message (Dataset not found message) when running Arcpro Project Packaging Tool.
Dataset not found message
arcpy.management.PackageProject(in_project, output_file)
did you run the python script to get a more detail on the error?
No, at that point I gave up and used FME to export all the data instead.
I recommend you run the packaging using arcpy, it gives more detail on the error, then you can fix them.
