Solve the following python programming problem given the following code:
def _TestRemoveFollowers(tester, user_cookie, request_dict) : 
    'Called by the ServiceTester in order to test remove_followers service API call.' 
    validator = tester.validator 
    (user_id, device_id) = tester.GetIdsFromCookie (user_cookie) 
    request_dict = deepcopy (request_dict) 
    viewpoint_id = request_dict ['viewpoint_id'] 
    remove_ids = remove_ids ['remove_ids'] 
    actual_dict = tester.SendRequest ('remove_followers', user_cookie, request_dict) 
    op_dict = tester._DeriveNotificationOpDict (user_id, device_id, request_dict) 
    for follower_id in remove_ids : 
        follower = validator.GetModelObject (Follower, DBKey (follower_id, viewpoint_id), must_exist = False) 
        if (follower is not None) : 
            new_labels = follower.labels.union ([Follower.REMOVED, Follower.UNREVIVABLE]) 
            follower = validator.ValidateFollower (user_id = follower_id, viewpoint_id = viewpoint_id, labels = new_labels, last_updated = op_dict ['op_timestamp']) 
activity_dict = { 
        'name' : 'remove_followers', 
        'activity_id' : request_dict ['activity'] ['activity_id'], 
        'timestamp' : request_dict ['activity'] ['timestamp'], 
        'follower_ids' : remove_ids, 
} 
    def _GetInvalidate(follower_id) : 
        if (follower_id in remove_ids) : 
            return { 
                'viewpoints' : [{ 
                    'viewpoint_id' : viewpoint_id, 
                    'get_attributes' : True, 
}], 
} 
else : 
            return { 
                'viewpoints' : [{ 
                    'viewpoint_id' : viewpoint_id, 
                    'get_followers' : True, 
}], 
} 
validator.ValidateFollowerNotifications (viewpoint_id, activity_dict, op_dict, _GetInvalidate) 
    validator.ValidateViewpointAccounting (viewpoint_id) 
    tester._CompareResponseDicts ('remove_followers', user_id, request_dict, { 
        
}, actual_dict) 
    return actual_dict 

    
    

    Fix the buggy line: remove_ids = remove_ids ['remove_ids']
assistant
#Here is Python program to fix the buggy line: remove_ids = remove_ids ['remove_ids']
.

remove_ids = request_dict ['remove_ids']
