Finding who INVITED you :: Facebook FQL Explorer Bug: "Inviter":null

Question

Similar unanswered question, however this question focusing more on where to proceed to now. I am led to believe that there is a bug with Facebook's FQL because the event_member table never returns a non-null answer for "inviter", [tested large and small events, public & private, and self admined events]. There are no reported "inviter" bugs on Facebook's site, and no references elsewhere on the internet. Is it common for Facebook to have an error in their graph ( I should hope not)? Could it be this is now depreciated (With no mark of it's existence)? Should I wait it out or keep trying? If it is a brand new feature of event_member, should there not be a news release etc?

TRY this example on Facebook's FQL explorer: https://developers.facebook.com/tools/explorer?fql=select%20inviter%2C%20inviter_type%2Cuid%2C%20rsvp_status%20from%20event_member%20where%20eid%20%3D%20321938874572158%3B

TL;DR: This doesn't work: Select inviter, inviter_type,uid, rsvp_status from event_member where eid = 321938874572158;

Answer 1

The graph returned for the inviter field only reports the ONE person who FIRST invited YOU, not anyone else. If you created the event yourself, or "attended" the event without an invite (such as by finding the link), then you wont have an "inviter". So to answer your question, there is not a "crippling bug".

For the part of actual graph results returned shown below:

• I have been invited 3 times,though only one ID shows up.
• It has a privacy level of "friends of friends".
• I am attending.

• The command used was SELECT uid, rsvp_status, inviter FROM event_member WHERE eid=5612079XXXXXXXX;

  {
  "uid": 51454XXXX,
  "rsvp_status": "attending",
  "inviter": null
  },
  {
  "uid": 3124XXXX,
  "rsvp_status": "attending",
  "inviter": 16498XXXX                   <------ HERE IS MY INVITE, FROM ANOTHER USER
  
  },
  {
  "uid": 127868XXXX,
  "rsvp_status": "attending",
  "inviter": null
  },
  {
  "uid": 164982XXXX,
  "rsvp_status": "attending",
  "inviter": null
  }
