Exception ProjectError: Failed to save copy

I just tried out this example from the following documentaion path

C:\Program Files\Adobe\Adobe Substance 3D Painter\resources\python-doc\substance_painter\project.html?highlight=template

I changed where the paths of the where all the assets exist.

import substance_painter.project

# A few declarations used in this example:
workFolder = "C:/temp"
meshFile = workFolder+"/test.fbx"
templateFile = workFolder+"/test.spt"
mySettings = substance_painter.project.Settings(
    import_cameras=True,
    normal_map_format=substance_painter.project.NormalMapFormat.OpenGL)

substance_painter.project.create(mesh_file_path=meshFile, settings=mySettings)
# Save the project to a file:
substance_painter.project.save_as(workFolder+"/test.spp") # No errors

import substance_painter.project;substance_painter.project.save_as(r"C:\temp\test.spp")
