All other endpoints I've tried are working fine and I am logged in but when user either of the following:

"get_followers": {
"endpoint": "users/%s/followers",
"request_type": "get",
"url_params": ["user_id"],
"required_params": [],
"optional_params": [],
"model": "UserCollection"
},
"get_following": {
"endpoint": "users/%s/following",
"request_type": "get",
"url_params": ["user_id"],
"required_params": [],
"optional_params": [],
"model": "UserCollection"
},

I get this response:

{
"code": 100,
"data": "",
"success": false,
"error": "You must be logged in to perform this action."
}
