json.decoder.JSONDecodeError: Expecting value: line 3 column 1 (char 4)

Question

I have written a script which is hitting Azure DevOps API and get API response from it. The script is working file on local machine but when I am trying to run the same script from Azure pipeline it is giving me error.

Traceback (most recent call last):
  File "/azp/$AZP_AGENT_NAME/3/s/terra/agent/agent_queue_status.py", line 19, in <module>
    data = json.loads(r)
  File "/_work/_tool/Python/3.9.0/x64/lib/python3.9/json/__init__.py", line 346, in loads
    return _default_decoder.decode(s)
  File "/_work/_tool/Python/3.9.0/x64/lib/python3.9/json/decoder.py", line 337, in decode
    obj, end = self.raw_decode(s, idx=_w(s, 0).end())
  File "/_work/_tool/Python/3.9.0/x64/lib/python3.9/json/decoder.py", line 355, in raw_decode
    raise JSONDecodeError("Expecting value", s, err.value) from None
json.decoder.JSONDecodeError: Expecting value: line 3 column 1 (char 4)
##[error]Bash exited with code '1'.

This the my script:

import base64
import requests
import json


AZURE_DEVOPS_PAT = 'my_pat'
authorization = str(base64.b64encode(bytes(':' + AZURE_DEVOPS_PAT, 'ascii')), 'ascii')
headers = {
    'Accept': 'application/json',
    'Authorization': 'Basic ' + authorization
}

url = 'https://dev.azure.com/{MY-ORG}/(MY-Project)/_settings/agentqueues?__rt=fps&__ver=2'
r = requests.get(url, headers=headers).text
data = json.loads(r)

print(data)

I tried everything. Like changing the way of getting response but no luck.

tried:-
r = requests.get(url, headers=headers).json
-------------------------------------------
r = requests.get(url, headers=headers)
data = r.json()

Please suggest something. The code is working fine on local machine but not with pipeline on Azure agent.
