Empty user_name field in Get Followed Streams endpoint when channel first comes online

[Wallboy]

Brief description
When a channel first comes online, if you make a request to the Get Followed Streams endpoint, the user_name field will be an empty string for that channel.

How to reproduce
It's easy to reproduce:

Use a test account and follow yourself on another account. Go online on the test account and make a request to Get Followed Streams endpoint until the channel shows up. The user_name field will be an empty string. This problem persists when making the same request for roughly ~15-30 seconds until the problem fixes itself and the user_name will finally have the proper value.

Expected behavior
user_name field is not an empty string

Screenshots
Here is the JSON returned when the problem happens:

Additional context or questions
I noticed someone having a similar issue with the webhook that was posted nearly 3 years ago. I'm not sure if the problem is related.

Still not fixed. Both the user_name and tag_ids fields are empty/null.

Example response from a followed stream which has just come online:

{
	"id": "45250445197",
	"user_id": "26490481",
	"user_login": "summit1g",
	"user_name": "",
	"game_id": "138585",
	"game_name": "Hearthstone",
	"type": "live",
	"title": "chillin on hearth. !gfuel !merch - @summit1g",
	"viewer_count": 0,
	"started_at": "2022-01-22T23:15:17Z",
	"language": "en",
	"thumbnail_url": "https://static-cdn.jtvnw.net/previews-ttv/live_user_summit1g-{width}x{height}.jpg",
	"tag_ids": null,
	"is_mature": false
}

As a workaround, the users endpoint can be queried with the user_id, which is available (fortunately).

Still an issue

Unable to reproduce this when testing. Not sure if this is still an occurring issue.
