Trying to query all boards for specific Status column values

I am trying to get all tasks that have the “Status” column set to a specific value.

–
payload = {“query”: “{items_by_column_values(board_id: 226020274, column_id:"Status", column_value:"Done"){id name column_values{id value}}}”}

    r = requests.post(url_api, json=payload, headers=headers)

    print (r.text)

–
gets me :
{“data”:{“items_by_column_values”:},“account_id”:XXXXXX}

Where am i going wrong ? I am sure that the board id exists (tried with all my board_ids) and that the status column is that exact name
