"instagram graph api" (#100) Tried accessing nonexisting field (business_discovery) on node type (URL)

When I try to operate business_discovery api on Graph Api Explorer it return following error.
Please teach me how to get it work.

{"error": {
"message": "(#100) Tried accessing nonexisting field (business_discovery) on node type (URL)",
"type": "OAuthException",
"code": 100,
"fbtrace_id": "A72pX1O2G5lr7lRTPV1aUCz" }}

the request i'm sending is from business_discovery api page so i belive it correct.

my access token type are "Page" and it still valid.

(my user ID)?fields=business_discovery.username(bluebottle){followers_count,media_count}

I have following permission

• pages_show_listads_management
• business_management
• instagram_basic
• instagram_manage_comments
• instagram_manage_insights
• instagram_content_publish
• instagram_manage_messages
• pages_read_user_content
• pages_manage_engagement

From Docs - IG User Business Discovery, The endpoint is: GET /{ig-user-id}?fields=business_discovery.username({username}). Here, You need to use the IG User Id — an Instagram Business or Creator Account ID - that's connected to the Facebook Page. To get your IG User ID, you can follow the steps mentioned here.

The following request works for me:-

Request:-

GET /17841448XXXX?fields=business_discovery.username(bluebottle){followers_count,media_count,name}

Response:-

{
  "business_discovery": {
    "followers_count": 442424,
    "media_count": 2074,
    "name": "Blue Bottle Coffee",
    "id": "17841401441775531"
  },
  "id": "17841448XXXXXXX"
}

Hope this helps.
