Facebook Graph API return error when call Business Discovery API

When I call the api:

 graph.facebook.com/userid?fields=business_discovery.username(name){followers_count,media_count}

in Graph API explore, I got an invalid parameter error:

(#100) Tried accessing nonexisting field (business_discovery) on node type (User)

Could anyone please explain to me what I miss in the API url?

Thanks

This only works for Instagram Business Accounts, but you seem to be using it with a normal user id.

As https://developers.facebook.com/docs/instagram-api/reference/user/business_discovery says,

Instagram Platform API account IDs will not work with the new Instagram Graph API. Please use the Page node to determine the correct Instagram Business Account ID associated with the Facebook page.

You can not use this for other types of Instagram accounts, only for business accounts.
