VK API get audio not working?

Question

In contact with

I'm trying to get a list of the user's audio recordings:

'owner_id'         => $user_id,
'access_token'  => $access_token,
'extended'        => 1,
 'v'                   => '5.60',

I get this response:

array:1 [
  "response" => array:4 [
    "count" => 2
    "items" => []
    "profiles" => array:1 [
      0 => array:8 []
    ]
    "groups" => []
  ]
]

I have 2 groups in my audio recordings, which is what is shown in count, but items is empty. What am I doing wrong?

Answer 1

"Withdrawn" entries were not displayed. The rest are taken out.
