Problem during inference with VLEP

I processed with the indicates jupyter file the data , I have something like this:
{"video": "friends_s03e09_seg02_clip_07_ep", "num_option": 2, "qid": "VLEP_20142", "a0": "Ross will stop, turn and point at Monica.", "a1": "Ross will stop and ask Monica why she is pointing at him.", "answer": 0, "start": 38.81, "end": 40.37}

but during inference I get an error:

File "/SeViLA/lavis/datasets/datasets/mc_video_vqa_datasets.py", line 54, in __getitem__
q = ann['question']
KeyError: 'question'

if you go to that file you have:

You can see that line 54 is asking for ann['question'] that vlep does not have. I do not know if I forgot to set some path or variable or something.

Thanks in advance.
