Exception(f"at index {i}") from se Exception: at index 0

I am trying to convert this Kitti Road/Lane Detection Evaluation 2013 to Pascal voc like dataset.

I have renamed calib folders (found under training and testing folders) to label_2 and I have created the train.txt like it was instructed. The first lines of train.txt are the following:
um_000000
um_000001
um_000002
um_000003
um_000004
um_000005
um_000006
um_000007

When I convert it I get the following validation error:

INFO:root:Namespace(filter_images_without_labels=False, from_key='kitti', from_path='./Kitti/data_road', select_only_known_labels=False, to_key='voc', to_path='./Kitti-voc')

On instance['detections'][1]['left']:

The above exception was the direct cause of the following exception:

Traceback (most recent call last):
File "../vod-converter-master/vod_converter/main.py", line 92, in
filter_images_without_labels=args.filter_images_without_labels))

raise Exception(f"at index {i}") from se

Could you tell me please what did I miss or this converter is intended to be used only with these Kitti datasets:

• KITTI
• KITTI tracking

Thank you.
