How to set datasets.features

Beginners
1

Hi HF community! I have .jsonl dataset which has every line just like:

{‘gt_parse’: {
‘company’: ‘KUAFOR’,
‘vergiDairesiNO’: ‘32969258048’,
‘tarih’: ‘24-07-2023’,
‘fisNO’: ‘FİS NO:4’,
‘toplamKDV’: ‘KDV *0,00’,
‘toplamTutar’: ‘TOP *550,00’,
‘items’: [{‘kdvUrunu’: ‘ROFLE’, ‘kdvYuzdesi’: '% ', ‘kdvTutar’: ‘*550,00’},
{‘kdvUrunu’: ‘OJE’, ‘kdvYuzdesi’: ‘%1’, ‘kdvTutar’: ‘*120,00’} ]},
‘meta’: {‘image_id’: 181, ‘image_size’: {‘width’: 430, ‘height’: 1591}, ‘split’: ‘train’}}

I am developing a loading script but i get an error while i am loading the dataset. I have set loading class _info method like following script, what’s wrong with this? Especially i am suspicious about ‘items’ key. How can i define this key accurately? I would be appricate any help.

def _info(self):
    return datasets.DatasetInfo(
        description=_DESCRIPTION,
        features=datasets.Features(
            {
                "gt_parse": datasets.features.Sequence(
                    {
                        'company': datasets.Value("string"),
                        'vergiDairesiNO': datasets.Value("string"),
                        'tarih': datasets.Value("string"),
                        'fisNO': datasets.Value("string"),
                        'toplamKDV': datasets.Value("string"),
                        'toplamTutar': datasets.Value("string"),
                        'items': datasets.features.Sequence(
                    {
                        "kdvUrunu": datasets.Value("string"),
                        "kdvYuzdesi": datasets.Value("string"),
                        "kdvTutar": datasets.Value("string")
                    })
                    }),
                "meta": {
                    'image_id': datasets.Value("int64"), 
                    'image_size': datasets.features.Sequence(
                        {
                            'width': datasets.Value("int64"), 
                            'height': datasets.Value("int64")
                            }),
                    'split': datasets.Value("string")
                            }
                            }),
