Modify Channel with empty tags array not working

[chillymosh]

Brief description Using the modify channel information endpoint PATCH https://api.twitch.tv/helix/channels and passing an empty array for tags does not remove all the tags, it returns error 400.

{"error":"Bad Request","status":400,"message":"The request must update at least one channel property field."}

If you pass in multiple fields then it does update them but ignores the empty tags array and it remains in the existing state.

curl -X PATCH 'https://api.twitch.tv/helix/channels?broadcaster_id=<id>' \
-H 'Authorization: Bearer <bearer>' \
-H 'Client-Id: <client_id>' \
-H 'Content-Type: application/json' \
--data-raw '{"title":"there are helicopters in the game?", "broadcaster_language":"en", "tags":[]}'

How to reproduce

curl -X PATCH 'https://api.twitch.tv/helix/channels?broadcaster_id=<id>' \
-H 'Authorization: Bearer <bearer>' \
-H 'Client-Id: <client_id>' \
-H 'Content-Type: application/json' \
--data-raw '{"tags":[]}'

Expected behavior This should remove all the tags for the channel.

Something I've been doing in the mean time to clear tags is setting the default language tag that Twitch automatically applies to a channel anyways. As long as you know a channels language this is an easy way to remove all tags in one request.
