dj_rest_auth (jwt) refresh token is empty when login - django rest framework

im having a trouble with dj_rest_auth jwt package. when i signup for a new account it gives me both access token and refresh token in response, but when i try to login with credentials, all i get is access token, and refresh token is entirely empty! i configured the code as described in the documentation and the the tutorial that im following. Any idea about this problem? please let me know.

UPDATE: i just found that refresh token has been set correctly in the response header, but i cant figure out why its not in the response body and its shown empty?!

SITE_ID = 1

REST_AUTH = {
    'USE_JWT': True,
    'JWT_AUTH_COOKIE': 'access',
    'JWT_AUTH_REFRESH_COOKIE': 'refresh',
}

Response:

{
    "access_token": "eyJhbGciOiJ.....",
    "refresh_token": "",
    "user": {
        "pk": 2,
        "username": "test_user_0",
        "email": "test0@mysite.co",
        "first_name": "",
        "last_name": ""
    }
}

REST_AUTH = {
    'USE_JWT': True,
    'JWT_AUTH_HTTPONLY':False
} 

change your rest_auth configuration to this then it should work

The AUTH_HTTPONLY configuration is expressly for disallowing access to the refresh_token for client-side JS. If you want it to only be managed through a cookie, do not change this, if you want to manage your auth state in your JS, you need to change it.
