doods2: Exception in ASGI application

Hi there!

Thanks for this amazing package!

I’ve got it installed on Home Assistant and the default models work - i.e. I can detect a bike etc.

I wanted to add a custom model, but I’m getting an “Exception in ASGI application” when I try to run the image.

To confirm

• The doods webpage loads, and the configuration loads.
• I can see my model loaded with the labels. I can do a “default” image with the same image no problem.

Below is the full log.

Attached is the model.
