我试图从一个网站上抓取有关圣经注解的信息。下面是我为此所做的代码。start_urls是我试图抓取的json文件的链接。我选择了['0']['father']['_id']来获取评论者的名称，但是，出现了下面的错误。我该怎么办？
错误：TypeError: list indices must be integers or slices, not str
编码：

import scrapy
import json

class catenaspider(scrapy.Spider): #spider to crawl the url
    name = 'commentary' #name to be called in command terminal
    start_urls = ['https://api.catenabible.com:8080/anc_com/c/mt/1/1?tags=[%22ALL%22]&sort=def']

    def parse(self,response):
        data = json.loads(response.body)
        yield from data['0']['father']['_id']```
