我想知道为什么当我在此数据集上使用 record_path 时会出现关键错误。 它来自 FDA api，我抓取了前两个结果。

在 results 键下有 2 个嵌套键，分别名为“active_ingredients”和“packaging” 当我正常化时我得到
result = pd.json_normalize(data['results'], record_path=["packaging"],meta=['product_ndc'])
预期的列
package_ndc description marketing_start_date sample marketing_end_date product_ndcs
但是当我将 active_ingredients 添加到 record_path 列表中时，我收到一个关键错误。 对于元来说也是如此。 当我将“brand_name”和“generic_name”等其他列添加到元列表时，我收到一个关键错误。 查看钥匙
这不起作用
result = pd.json_normalize(data['results'], record_path=["packaging","active_ingredients"],meta=['product_ndc','brand_name','generic_name'])
感谢您的帮助
当您指定多个 record_path 条目（如
"packaging""active_ingredients"record_path"active_ingredients""packaging"active_ingredients这样做可以解决这个问题
