[Python Script] Have trouble to export textures using python via Substance 3D Painter 8.2

Hi, there

Currently, I'm using Substance 3D Painter 8.2 to do some export jobs. But I Found I couldn't use my previous code that worked perfectly before. 

I have already changed the 'shelf' to 'starter_assets'

Mention: I have to use my own template to export the texture. "myTemplate" is my template.

[Python]   File "C:\Program Files/Adobe/Adobe Substance 3D Painter/resources/python/modules\substance_painter\export.py", line 194, in export_project_textures

[Python] *_substance_painter.export.export_project_textures(json.dumps(json_config)))
[Python] ValueError
[Python] : 
[Python] For exportList item #0, the preset "resource://shelf/myTemplate" is undefined
