Not getting "from" attribute in facebook comments

Question

I'm using facebook API v9.0 to get posts and comments associated with it using the page token.

The issue is such that I'm unable to get the 'from' attribute or in other words, the author of the comments in the response. I'm not sure what I'm missing here, please advice.

The cURL request is as below: 995833924237049 is the post_id

curl -i -X GET \
 "https://graph.facebook.com/v9.0/995833924237049/comments?fields=from&access_token={access_token}"

The response is as below from Graph API Explorer:

{
  "data": [
    {
      "id": "995833924237049_819251442244461"
    },
    {
      "id": "995833924237049_998774397276335"
    },
    {
      "id": "995833924237049_998772833943158"
    },
    {
      "id": "995833924237049_998781380608970"
    },
    {
      "id": "995833924237049_998776877276087"
    },
    {
      "id": "995833924237049_998782583942183"
    },
    {
      "id": "995833924237049_998781987275576"
    },
