Sometimes I see this JSONDecodeError and sometimes I don't

I am trying to fetch data from an API using Requests in python. Sometimes it works fine and sometimes it throws this error:

raise JSONDecodeError("Expecting value", s, err.value) from None
json.decoder.JSONDecodeError: Expecting value: line 1 column 1 (char 0)

I can't figure out what's the problem here, can anyone help me out.
Here's the API

Here is my code:

import requests
import json

headers = {'User-Agent': 'Mozilla/5.0'}
payload = {'symbol':'NIFTY'}
r = requests.get('https://www.nseindia.com/api/option-chain-indices', params = payload, headers = headers).json()

print(r.keys())
print(r['records'])

Because you need to set cookies to make this website work.

To do so with requests, you need to use a session.

import requests

s = requests.session()

headers = {'User-Agent': 'Mozilla/5.0'}
s.get("https://www.nseindia.com", headers=headers)  # set cookies

payload = {'symbol':'NIFTY'}
r = s.get('https://www.nseindia.com/api/option-chain-indices', params=payload, headers=headers)
r.json()  # will display content
