menuByName does not work on custom menus

I have tested this with the latest 1.0.0 version and it works for me.

2 things to consider:
Did you implement an access hook for the menu? Maybe you have an access hook only allowing view access on "main"?
https://graphql-core-schema.netlify.app/basics/security.html

/**
 * Implements hook_ENTITY_TYPE_access().
 */
function MY_MODULE_menu_access(EntityInterface $entity, $operation, AccountInterface $account) {
  // Grant view access to the main menu to everyone.
  $id = $entity->id();
  if ($operation === 'view' && $id === 'main') {
    return AccessResult::allowed();
  }

  return AccessResult::neutral();
}

Do you have a very cryptic broken machine nime that might give you troubles?

I restested and ti's not a custom or non custom menu qustion

Access Permission are already implemented and worked before. (As said it worked on Beta 7)

I may be related to the menu names but I couldn't fin a pattern

for Example a menu called test-test-test

query getMenu {
  menuByName(name: TEST_TEST_TEST) {
    id
    label
  }
}

works

but not a menu called menu-espace-membres

query getMenu {
  menuByName(name: MENU_ESPACE_MEMBRES) {
    id
    label
  }
}
