在使用json_normalize时遇到了非常典型的键错误。我已经设置了errors =“ ignore”。不幸的是，这仅适用于记录值，而不适用于元值。有没有人找到使meta字段可选的有效方法？我的目标是使用客户端关心的每个可能的字段查询json文件，并为缺少的内容返回NaN。
我的示例用法：
df = json_normalize(data, ['invoice-lines', 'account-allocations'], parent_fields , meta_prefix='invoice_', record_prefix='alloc_', errors='ignore')
我的示例错误：
KeyError：“标头税率”
我的“父字段”，元字段的长列表：
