ValueError：值的长度与索引的长度不匹配-json_normalize

Question

我正在使用以下代码来解析对熊猫数据框的json响应，然后转换嵌套的json'terms'

示例json：

{
"conditions": [
    {
      "id": 3855792,
      "type": "apm_app_metric",
      "name": "Error percentage (2.5%)",
      "enabled": true,
      "entities": [
        "3418936",
        "39720385",
        "70369692",
        "3242026",
        "3744556",
        "5673838"
      ],
      "metric": "error_percentage",
      "condition_scope": "application",
      "terms": [
        {
          "duration": "5",
          "operator": "above",
          "priority": "critical",
          "threshold": "2.5",
          "time_function": "any"
        }
      ]
    }
  ]
}

代码：

import requests
import json
import pandas as pd,os
from pandas.io.json.normalize import json_normalize

json_data = json.loads(response.text)
terms_data = json_normalize(data = json_data['conditions'], 
                            record_path = 'terms',
                            meta = ['condition_scope', 'enabled', 'id', 'metric', 'name', 'type', 'entities'])

但是，该脚本在尝试将“实体”解析到数据框中时失败，并出现以下错误

    meta = ['condition_scope', 'enabled', 'id', 'metric', 'name', 'type', 'entities'])

    result[k] = np.array(v).repeat(lengths)

  File "C:\Users\M1049639\AppData\Local\Programs\Python\Python37-32\lib\site-packages\pandas\core\frame.py", line 3194, in _set_item
    value = self._sanitize_column(key, value)
  File "C:\Users\M1049639\AppData\Local\Programs\Python\Python37-32\lib\site-packages\pandas\core\frame.py", line 3391, in _sanitize_column
    value = _sanitize_index(value, self.index, copy=False)
  File "C:\Users\M1049639\AppData\Local\Programs\Python\Python37-32\lib\site-packages\pandas\core\series.py", line 4001, in _sanitize_index
    raise ValueError('Length of values does not match length of ' 'index')
ValueError: Length of values does not match length of index

所需的输出： output

最终输出： output
