KeyError: 'id'

When I apply the FewX on custom dataset, I meet an error:

Traceback (most recent call last):

id = dataset_dict['annotations'][0]['id']
KeyError: 'id'

I print the dataset_dict as follow:

{'file_name': 'datasets/my_data/support/train2017/9838da66b7ca2606a418900fd6c33f34.jpg', 'height': 800, 'width': 800, 'annotations': [{'iscrowd': 0, 'bbox': [38, 40, 109, 141], 'category_id': 5, 'bbox_mode': <BoxMode.XYWH_ABS: 1>}, {'iscrowd': 0, 'bbox': [466, 391, 15, 29], 'category_id': 5, 'bbox_mode': <BoxMode.XYWH_ABS: 1>}]}

In dataset_dict['annotations'], there is no item called 'id', but in my json file the 'id' is included.

{"height": 800, "width": 800, "id": 635, "file_name": "9838da66b7ca2606a418900fd6c33f34.jpg"}
{"id": 1554, "image_id": 635, "category_id": 6, "segmentation": [[38, 40, 38, 110.5, 38, 181, 92.5, 181, 147, 181, 147, 110.5, 147, 40, 92.5, 40]], "bbox": [38, 40, 109, 141], "iscrowd": 0, "area": 15620}, {"id": 1555, "image_id": 635, "category_id": 6, "segmentation": [[466, 391, 466, 405.5, 466, 420, 473.5, 420, 481, 420, 481, 405.5, 481, 391, 473.5, 391]], "bbox": [466, 391, 15, 29], "iscrowd": 0, "area": 480},

Would you please explain why there is no 'id' in the dataset_dict['annotations']?

I have the same problem, have you solve it?
