I want to use Rasa NLU server only for my custom dialogue management , which is written in a python code. For that i want to post messages to the nlu server and get the intent rankings. I tried -

```auto
text=str(input("Enter the message"))
payload = json.dumps({"sender": "Rasa","message": text})
headers = {'content-type': 'application/json'}
response = requests.request("POST",'http://10.101.1.239:5005/model/parse', json=payload, headers=headers)
response = response.json()
print("response :\n",response)

```

However it throws an error, -

> response : {‘version’: ‘2.8.18’, ‘status’: ‘failure’, ‘message’: ‘An unexpected error occurred. Error: string indices must be integers’, ‘reason’: ‘ParsingError’, ‘details’: {}, ‘help’: None, ‘code’: 500}

But if the payload is -

```auto
payload = {'text':'hi how are you?'}
headers = {'content-type': 'application/json'}
r = requests.post('http://10.101.1.239:5005/model/parse', json=payload, headers=headers)

```

then i get the list of intent rankings properly.

The sender id is necessary as I am trying to manage dialogues externally through my code. Please help
