Can not load model - Python error

Speckle Help
1

Hello,

i want to test the pipeline from converting an nwd to blender. I am a long time user of Blender and addons. I have Blender 4.2.12 LTS and 4.5.10 LTS installed. The later completly vanilla.
I downloaded and installed speckle.blender.installer-3.5.1.exe and the plugin had no issues to be activated. I could login inside of blender and choose the project and model.

When i try to load the model i get this error:

Python: Traceback (most recent call last):
  File "C:\Users\livei\AppData\Roaming\Blender Foundation\Blender\4.5\scripts\addons\bpy_speckle\connector\blender_operators\model_card_load_button.py", line 49, in execute
    converted_objects = load_operation(
                        ^^^^^^^^^^^^^^^

                         ^^^^^^^
TypeError: '<' not supported between instances of 'NoneType' and 'str'

Its on both Blender versions.

I checked the Speckly system status and there were no errors

Anyone else experience that ?

Our NWD importer appears to be creating a collection with a null name, which is unexpected.
We will investigate more…

Hey,
any news here?

A fix has been made on our end to ensure that the Collection name is properly set from the NWD file importer.
The update should become live by tomorrow, I’ll let you know when it is.

Unfortunately it will necessitate you re-uploading affected models. Hopefully this isn’t too much of an inconvenience.

The changes has now been deployed to https://app.speckle.systems
New NWD/NWC uploads will fully populate Collection.name property ensuring they can be received by python clients like the Blender connector.

Please re-upload your NWD models, and then you should be able to receive them.
