I want to check the list of live broadcasts in the LOL game section of the game category through YouTube API.
I live in Korea, and the url is as follows.
https://www.youtube.com/channel/UCZtmNrG53nmbq-Ww2VJrxEQ (It is maybe auto generated channels)

I ran the API from this page (https://developers.google.com/youtube/v3/docs/search/list?hl=ko).
Value is part=snippet, channelId=UCZtmNrG53nmbq-Ww2VJrxEQ, eventType=live, type=video

but, I got the value as follows.

{
  "kind": "youtube#searchListResponse",
  "etag": "jY03jGgN1g_xKk8RSHyjN_PoL8I",
  "regionCode": "KR",
  "pageInfo": {
    "totalResults": 0;
    "resultsPerPage": 0
  },
  "items": []
}

There is clearly something live broadcasting, but it passes an empty value.

I don’t know what I did wrong

I think the search api doesn’t support auto-generated channels.

I want collect live streams data list.
