unable to send refresh and access tokens together in same authentication route

[yeti9990]

I'm using:

fastapi              0.108.0
fastapi-jwt          0.2.0
python-jose          3.3.0

on Mac OS, python 3.10.13. I'm not able to get the refresh_token cookie set... using:

@router.post("/users/login", status_code=status.HTTP_200_OK)
def login(
        user: UserLogin,
        response: Response,
        session: Session = Depends(get_db)
):
    rec = UserService(session).authenticate_user(user=user)
    if not rec:
        raise HTTPException(status_code=404, detail="User does NOT exist in the system")
    rec = jsonable_encoder(rec)
    subject = {
        'username': rec.get('username'),
        'role': rec.get('role'),
        'departments': rec.get('departments')
    }

    access_token = access_security.create_access_token(subject=subject, expires_delta=timedelta(minutes=1))
    refresh_token = refresh_security.create_refresh_token(subject=subject, expires_delta=timedelta(minutes=2))

    access_security.set_access_cookie(response=response, access_token=access_token)
    refresh_security.set_refresh_cookie(response=response, refresh_token=refresh_token)

    return {'user': rec, 'access_token': access_token, 'refresh_token': refresh_token}

Both show up in the JSON response, but ONLY access_token_cookie cookie is set. If i switch the order of the set_*_cookie() calls, the refresh_token_cookie is set but not access_token_cookie.

I've seen it work, but can't fig. out how or why it's failing to send both now. I'm attempting to use the JwtRefreshBearerCookie.
