Making get request for creating page-access-token for facebook graph API returns blank data object.

The request is like below according to the official doc:https://developers.facebook.com/docs/facebook-login/guides/access-tokens/#pagetokens

curl -i -X GET "https://graph.facebook.com/{your-user-id}/accounts?access_token={user-access-token}"

This worked at least half years ago, now the request returns blank data[] object.
I tried both curl command line and Graph API Explorer.

Any ideas to solve this issue?
