Test drive question

Hello:

I am trying to connect “test-drive.collibra.com” from my python notebook using the below, code is not working. I am getting errors as shown below. Am I missing something or doing wrong?

Any help is greatly appreciated.

Code:-
owl = “https://”
url = “https:///auth/signin”
payload = json.dumps({
“username”: “”, # Edit Here
“password”: “”, # Edit Here
“iss”: “public” # Edit Here
})
headers = {
‘Content-Type’: ‘application/json’
}
response = requests.request(“POST”, url, headers=headers, data=payload, verify=False)
owl_header = {‘Authorization’: 'Bearer ’ + response.json()[‘token’]}

ERROR:-
JSONDecodeError: Expecting value: line 1 column 1 (char 0)

During handling of the above exception, another exception occurred:

JSONDecodeError Traceback (most recent call last)

17 }
