Facebook api – How to get public info from Facebook Graph API v20.0?

So I create an App. I get an access_token, specifying "pages_read_engagement". For good measure, using my app-id and app-secret, I get a long term token. I then make a simple request

    curl -i -X GET "https://graph.facebook.com/v20.0/100057751132253?access_token=REDACTED"

and I get the response

    {"error":{"message":"Unsupported get request. Object with ID '100057751132253' does not exist, cannot be loaded due to missing permissions, or does not support this operation. Please read the Graph API documentation at https://developers.facebook.com/docs/graph-api","type":"GraphMethodException","code":100,"error_subcode":33,"fbtrace_id":"AGSkkLP2xPncRE9SS4nAMZT"}}

Now I happen to know that 100057751132253 resolves to KevinMichelMLA, a state-level politician in the Australian state of Western Australia. As far as I can tell, his profile is public. And I have at least one of the required permissions. What else am I missing?

    For public information, you typically don’t need an access token. However, if the information is behind certain privacy settings, you might need specific permissions. Here are some permissions you might consider:

    public_profile: Access the public profile of a user.

    pages_read_engagement: Read content from pages you manage.

    Debugging Steps

    1. Verify ID: Ensure that 100057751132253 is the correct ID for KevinMichelMLA. Sometimes IDs can change, or there might be a typo.
    2. Graph API Explorer: Use the Graph API Explorer to test your requests. This tool can help you identify permission issues and ensure that your access token is valid.
    3. App Review: Make sure your app has been approved for the permissions you are requesting if they require app review.
    4. Check Rate Limits: Ensure you are not hitting any rate limits for the Graph API.

    This is a page, not a user profile.

    Apps do not get access to pages the user has no admin access to any more, even if they are public – unless the app gets the Page Public Content Access feature approved by Facebook.
