Hi @fkseki ,

Since filter_by is an object parameter in a GET request, I think that you need to convert it to a JSON string when passing it as a query parameter. Try to do something like this:

filter_by_json = json.dumps({"policy_name": "aaaa"})
params = {"filter_by": filter_by_json}
response = requests.get(url=url, headers=headers, params=params)
