I am trying extract data from website using request and bs4 python module. when i try to access this code, got below error message to json

capcha2 = requests.post(url=url1,headers=headers3,data=payload1)
print(capcha2)
cap = json.loads(capcha2.text)
captcha_status = cap['required']
print(captcha_status)

when i try to load value to json, got below error message.

Traceback (most recent call last):
  File "C:\Users\Madeena\PycharmProjects\pythonProject\pythonProject2\ahamed3.py", line 39, in <module>
    cap = json.loads(capcha2.text)
