Facebook Graph API Comments not returning - facebook

Question

I am trying to get the comments on ratings from the Facebook API.
First I request a list of ratings for a page I own:
https://graph.facebook.com/v3.0/me/ratings?fields=open_graph_story?access_token=[access_token]
Response:
{
"data": [
{
"open_graph_story": {
"message": "The best place in the world(s), and this is to reach that limit in the facebook review.",
"start_time": "2018-05-24T22:56:23+0000",
"type": "pages.rates",
"data": {
"rating": {
"value": 5,
"scale": 5
},
"review_text": "The best place in the world(s), and this is to reach that limit in the facebook review.",
"is_hidden": false,
"language": "en"
},
"id": "1805660589743235"
}
},
{
"open_graph_story": {
"message": "Very good, not excellent though. Does Facebook change the created time if I edit this?",
"start_time": "2018-04-12T20:25:26+0000",
"type": "pages.rates",
"data": {
"rating": {
"value": 3,
"scale": 5
},
"review_text": "Very good, not excellent though. Does Facebook change the created time if I edit this?",
"is_hidden": false,
"language": "en"
},
"id": "106674383523012"
}
}
],
"paging": {
"cursors": {
"before": "MTAwMDA4OTc5MzQ4Mjc3Ojc3MzQwNTI3NjIwMTQyNAZDZD",
"after": "MTAwMDI1NDEzNTE3NzgxOjc3MzQwNTI3NjIwMTQyNAZDZD"
}
}
}
(I removed some superfluous fields)
Then I use the id from the open_graph_story to get the comments for a rating:
https://graph.facebook.com/v3.0/106674383523012/comments?access_token=[access_token]
Response:
{
"data": [
],
"paging": {
"cursors": {
"before": "WTI5dGJXVnVkRjlqZAFhKemIzSTZANVFF5T1RNeU1UUTVPRGszTWpNMU9qRTFNalkwT0RZAeE1qZAz0ZD",
"after": "WTI5dGJXVnVkRjlqZAFhKemIzSTZANVFE0TlRBM09URXlOamN5T1RreU9qRTFNamN5TURJek56ST0ZD"
}
}
}
It returns no data even though I can see comments on the actual rating when I visit the Facebook page. Why are no comments returned?
(Just to make sure that I had the correct permissions, I selected all the permissions possible in the graph api explorer.)
