What happened to the VK API with attachments?

Question

In contact with

I do not understand what the problem is, everything seemed to work before.
From the server I send data to wall.post text + picture, the picture was loaded before that, after adding the post is created, the text is there, but the picture is not.
Steps:
1. I take the picture on the server
2. I get a link to the upload form (photos.getWallUploadServer)
3. I upload the picture from the link (from the received link)
4. I save the picture (photos.saveWallPhoto)
In the response I get

{ response:
   [ { id: 456XXXXX,
       album_id: -14,
       owner_id: 578XXXXX,
       photo_75: 'https://pp.userapi.com/XXXXX_c.jpg',
       photo_130: 'https://pp.userapi.com/XXXXX_c.jpg',
       photo_604: 'https://pp.userapi.com/XXXXX_c.jpg',
       width: 604,
       height: 403,
       text: '',
       date: 1517946325,
       access_key: '8ad26XXXXXXX } ] }

5. Create a post on the wall

//https://api.vk.com/method/wall.post?owner_id=-XXXXXXXX&from_group=1&access_token=TOKEN&v=5.67
params.request.formData = {
        //message: post.text, // Убрал текст, так как с ним все ок
        attachments: attachments.join(',') // Так выглядит вложение photo-5XXXXXXX_4XXXXXXX
    }
    return request.post(params.request).then(e => {
        console.log(e.error)
    })

I get an error

{error_code: 100,
  error_msg: 'One of the parameters specified was missing or invalid: invalid message param',
  request_params:
   [ { key: 'oauth', value: '1' },
     { key: 'method', value: 'wall.post' },
     { key: 'owner_id', value: '-2XXXXXX' },
     { key: 'from_group', value: '1' },
     { key: 'v', value: '5.67' },
     { key: 'attachments', value: 'photo-5XXXXXXX_4XXXXXX' } ] }

What can be wrong?

Answer 1

At first, you have a positive owner_id (user), and then when posting it is already negative (communities).
