yolo11n-pose optimisation error

@omria @Nadav @nina-vilela @pierrem hey, trying to convert yolo11n-pose model with [5, 2] keypoints and 4 classes, run command to optimize model and get:

File “/local/workspace/hailo_virtualenv/lib/python3.10/site-packages/hailo_model_optimization/acceleras/model/hailo_model/model_flow.py”, line 181, in get_edge_output_index
return self.get_edge_data(u, v)[“output_index”]
TypeError: ‘NoneType’ object is not subscriptable

Before it, I had compiled another model with 6 classes and [4, 2] keypoints, and it was successful. Running with the use of the standard architecture of the model
