This looks a kind of duplicate question but actually NOT.
So the problem is https://www.facebook.com/julytalk/ has events, for sure. But when I tried on Facebook Group API toolkit, it returns empty array.
Why is this happening? I could not find any Facebook API endpoint modification notice, at all. It was working okay before.
Please help me.

Access to the Events API is not possible at the moment:
...apps currently accessing Events and Groups APIs will lose access today
Update: After Facebook did a lot of changes, it seems to be possible to get events again. You can get events from Pages you manage easily in dev mode. If you want to get public events, you may want to read the answer in this thread: Facebook pages API: "Page Public Content Access" review screencast
