為什麼文件當中有這個key，卻顯示keyerror

在用python写调用api来找数据的程式

import requests
import json
x = requests.get('https://api.hkma.gov.hk/public/market-data-and-statistics/daily-monetary-statistics/daily-figures-interbank-liquidity')
data=x.json()
overnightHIBORseries=data["hibor_overnight"]
print(overnightHIBORseries)
closingaggregatebalance=data["closing_balance"]
print(closingaggregatebalance)

报错：KeyError: 'hibor_overnight'

有人能帮忙看看吗

数据是嵌套在records里面的

import requests
import json
x = requests.get('https://api.hkma.gov.hk/public/market-data-and-statistics/daily-monetary-statistics/daily-figures-interbank-liquidity')
data=x.json()
print(data)

for i in data["result"]["records"]:
    overnightHIBORseries=i["hibor_overnight"]
    print(overnightHIBORseries)
    closingaggregatebalance=i["closing_balance"]
    print(closingaggregatebalance)
