Darshan Hiranandani : TypeError When Using create_filesystem_structure() in SGTK

Pipeline Integrations
1

Hi there,

I’m encountering an issue when trying to use the create_filesystem_structure() function within the Shotgun Toolkit (SGTK) to create and register directories for an asset. Here’s a simplified version of my code:

mgr = sgtk.bootstrap.ToolkitManager()
mgr.base_configuration = DESCRIPTOR_STRING
sg_asset = tk.shotgun.find_one(“Asset”, [[“id”, “is”, 100]])
tk.create_filesystem_structure(“Asset”, sg_asset[“id”])

When running this code in several different Python environments, I get the following stack trace:

arduino

~~~~~~~~~~~~~~^^^^^^
TypeError: ‘NoneType’ object is not subscriptable

It seems like there’s a problem with retrieving or processing the sg_asset data, but I’m not sure how to fix it.

Here are my questions:

  1. Why is project_entity being returned as None when attempting to access the id field, causing the 'NoneType' object is not subscriptable error?
  2. What could be the underlying cause of this issue when calling create_filesystem_structure() after retrieving the asset using tk.shotgun.find_one?
  3. How can I ensure that the asset is being correctly fetched from Shotgun before attempting to create the filesystem structure?

Any suggestions or insights would be greatly appreciated!

Best,
Regards
