According to Facebook graph API playground it is possible to search in a page/group feed , I'm using the following URL to do so:
https://graph.facebook.com/<group_id>/feed?q=<search query>&access_token=<access_token>
And this is the result i'm getting:
{
"error": {
"message": "An unknown error has occurred.",
"type": "OAuthException",
"code": 1,
"fbtrace_id": "FVaffSuGwvg"
}
}
What is the problem here ?
