Calling the API:

https:--graph.facebook.com-v21.0-{page-Id}?fields=access_token&access_token={system-user-token}

Expected behavior:

return

{

"access_token": "EAAG2vYOZCjGgBAFg..." (page token),

"id": "page-id"

}

Actual behavior:

{

"error": {

"message": "(#10) This endpoint requires the 'pages_read_engagement' permission or the 'Page Public Content Access' feature or the 'Page Public Metadata Access' feature. Refer to https:--developers.facebook.com-docs-apps-review-login-permissions#manage-pages, https:--developers.facebook.com-docs-apps-review-feature#reference-PAGES_ACCESS and https:--developers.facebook.com-docs-apps-review-feature#page-public-metadata-access for details.",

"type": "OAuthException",

"code": 10,

"fbtrace_id": "ArB-d5QtFSItpkqE9-jqFdd"

}

}

It tells me that the token does not have the pages_read_engagement permission. After checking (as shown in the attached picture), it is confirmed that the token has this permission. Is it a bug or other problem? Please help me solve this problem. Thank you very much.
