So you need to make sure you request the scope of offline_access in your first request to FusionAuth. That is in the initial request to the authorize endpoint:

http://localhost:9011/oauth2/authorize?client_id=64cbd582-9668-4a93-ad1f-28a78c6b95d3&redirect_uri=http%3A%2F%2Flocalhost%3A3000&response_type=code&scope=offline_access

When you are calling back for the token in your python call, you shouldn't need to specify the scope, it will already be associated with the code that FusionAuth has returned:

from fusionauth.fusionauth_client import FusionAuthClient
import json

code='XspK6zjeqSvXYlkHxrYChBdHM2-nmIjjI8DzbNLGgps'
client_id='64cbd582-9668-4a93-ad1f-28a78c6b95d3'
redirect_uri = 'http://localhost:3000'

client = FusionAuthClient('APIKEY', 'http://localhost:9011')

token = client.exchange_o_auth_code_for_access_token(code,redirect_uri, client_id)

print(json.dumps(token.success_response))
print(json.dumps(token.exception))
print(json.dumps(token.status))

I see the refresh token in the response using this code.
