facebook group members Bio information -

After

I am interested in retrieving bio information of members of a Facebook group .

I have created an app where I have requested permission of user_about_me and is being reviewed to present the application.

I have code for the application in JSP but can only select name, gender, last_name, first_name this bio information selection not doing.

I have the same problem in Graph API Explorer, when I use

  {group_ID} / members  

I I can retrieve the list of all group members. But I can not see more details than the following:

  "data": [{"name": "name", "administrator": wrong, "id": "USER ID" }, When I click on the ID (or I can enter an ID in Explorer), I can only get the following:  
  {"id": "member_ID", "first_name" : "Name", "update_time": "2015" - "firstname", "last_name": "alias", "link": "https: //www.facebook.com/app_scoped_user_id / ...", "name" 02-07T10: 02: 58 + 0000 "}  
 
 This  bio  is not showing information when I enter the following Ta I: 
 
  {member_ID}? Fields = bio  
 
 I just appreciate 
 
  {"id": "10153223503039309"}  
 
 I would appreciate it If someone recognizes the problem I believe that this problem will solve the problem of my code, at this time I am unable to recover the bioinformatics of the member of the group. 
 
 Is it possible that the problem is resolved after app approval?

You can only get more information from the user because it is a member of some groups. To get more data you must give it to your app with the correct permission.
