Access callback return true, but still is: you are not authorized to this page

Question

function updatable_news_menu() {
    $items['updatable_news/test'] = array(
        'title' => 'Updatable news',
        'page callback' => 'updatable_news_test',
        'access callback' => 'updatable_news_permission',
        'access arguments' => "hello",
    );
}
function updatable_news_permission() {
    return true;
}   

I have used a similar implementation and the permission is ok in another module. However, it fails in this module which defined a brand new entity.

function updatable_news_menu() {
    $items['updatable_news'] = array(
        'title' => 'Updatable news root',
        'page callback' => 'updatable_news_root',
        'access arguments' => true,
    );
}

I have to add new menu item with access should always be true. But it only succeed for administrator instead of anonymous user and logged in user.

Answer 1

'access arguments' must be an array. Like 'access arguments' => array('access administration pages')
