could not fetch info from comment table - facebook

Question

Facebook just notified me about "July 2013 Breaking Changes". There is one related to my app.
Deprecating 'comments' field from 'stream' FQL table
We are deprecating the 'comments' field from 'stream' FQL table. Please select the 'comment_info' column to fetch the 'can_comment' and 'comment_count' fields (formerly called 'can_post' and 'count'), and use the comment table directly to retrieve the list of comments.
In our app we are using query like this :
SELECT post_id, message, likes.count, comments.count, comments.comment_list FROM stream
WHERE source_id=me() AND actor_id=me() LIMIT 500
and receive response like this :
{
"data": [
{
**"post_id": "100002510712421_451594341600919",**
"message": "text",
"likes": {
"count": 1
},
"comments": {
"count": 2,
"comment_list": [
{
"fromid": 100001228089363,
"time": 1367073822,
"text": "text",
"text_tags": [
],
"id": "100002510712421_451594341600919_1181882",
"likes": 0,
"user_likes": false,
"post_fbid": 452073094886377
},
{
"fromid": 100000020227797,
"time": 1367173047,
"text": "text",
"text_tags": [
],
"id": "100002510712421_451594341600919_1183852",
"likes": 0,
"user_likes": false,
"post_fbid": 452790081481345
}
]
}
},
....
ok now try to fetch info from 'comment' table using given post_id
SELECT id, text, time, fromid FROM comment WHERE
post_id='100002510712421_451594341600919'
{
"data": [
]
}
The response is empty
Can anybody come up with solution? We really need it!

Answer 1

your query looks just fine, are you sure that this post_id exists and you have permission to read it?
SELECT id, text, time, fromid FROM comment WHERE
post_id='125909647492772_502974003098530'
returns
{
"data": [
{
"id": "502974003098530_78616446",
"text": "saugeil!",
"time": 1364309881,
"fromid": 526559276
}
]
}

Answer 2

I'veI run into the same issue.
Surprisingly, I was able to fix it by using only last part of the post_id, i.e.: '451594341600919' instead of '100002510712421_451594341600919'. But it works only sometimes and in your case doesn't work at all.
