Im trying to get all videos from YouTube auto-generated channel (AKA Topic).
I let my users add a link to the YT channel and I am sending the channel ID to retrieve videos.

On regular case, when the channel is NOT auto-generate I am using this endpoint:
<https://www.googleapis.com/youtube/v3/channels?part=snippet&channelId=>{channel\_id}&key={key}

This endpoint return a list of videos that posted into this channel.
The problem with topic is that the list of videos return empty...

**example for this following request:**
<https://www.googleapis.com/youtube/v3/search?part=snippet&channelId=UCYF2FotHeGO6cNcldrTHN1g&key=>{YOUR\_API\_KEY}

```
{
 "kind": "youtube#searchListResponse",

    "channelTitle": "",

   }
  }
 ]
}

```

Any idea how to get Topic videos?

Thanks
