"motion" model not loading.

[ryann0097]

Hope you are doing well. Today we tested a new deployment approach. Instead of installing the system inside a VM, we deployed it using Docker directly on a physical machine to speed up our debugging proccess.
The installation process was quick and completed without major issues. However, we are currently facing errors related to the "motion" detection model.
Please find below the relevant log excerpts:

From the logs, it appears that the system is unable to locate or load the "motion" model file, resulting in zero detections being recorded.
