Why is the photos.getUploadServer request to the VK API not processed?

Question

In contact with

I want to upload a photo to my public.
I enter the request as follows:
https://api.vk.com/method/photos.getUploadServer?g... token)
Response returned by the server:
{"error":{"error_code":200,"error_msg":"Access denied ","request_params":[{"key":"oauth","value":"1"},{"key":"method","value":"photos.getUploadServer"},{"key": "group_id","value":"-73346178"},{"key":"album_id","value":"197906416"}]}}
Photos permission granted. This query works when I enter my id and my album id in my account. That is, I can upload a photo to my album, but there is no community album. Maybe I'm doing something wrong?
