When I call the {user-id}/avatars interface, the following exception occurs. The token is the token of the public homepage, and the user id is the user id obtained by the comment post. How can I get the avatar of this user { "error": { "message": "Unsupported get request. Object with ID '8202582296432113' does not exist, cannot be loaded due to missing permissions, or does not support this operation.
