- Description
I run a request https://www.googleapis.com/youtube/v3/search with the parameter type=playlist.
That is, in the response I should get a list of playlists.
But one of the elements in the response is a channel, not a playlist ("kind": "youtube#channel").
This element should not be in the response.

- API request with parameters used (DO NOT include your credential)
https://www.googleapis.com/youtube/v3/search?part=snippet&q=Sports&key=[my_api_key]&type=playlist&relevanceLanguage=en&maxResults=50
