Why does VK_API users.get return an error?

Question

In contact with

the documentation says:

user_ids:
Default is the ID of the current user.

then why does https://api.vk.com/method/users.get return an error?

Answer 1

The previous answer was correct, but I will explain: Users.get can return data without a token, but in this case, you need to send one of the user ID parameters, if the token is specified -- ID can be omitted if you want to display information about the user, who took the token.

Answer 2

Because there is no access_token in the request, without it the API does not know on behalf of which user the request is being made
