[0.14.2] Headless Creating game fails with 401 http status

[Bisa]

I'm trying to start a server using a token in place of a password, but for some reason the server seems to be incorrectly omitting my username in the request to the matchmaking server

settings.json

{
"name": "Bisa's TestBox",
"description": "Test Server - Please ignore",
"tags": ["game", "tags"],
"max_players": "10",

"_comment_visibility": ["public: Game will be published on the official Factorio matching server",
"lan: Game will be broadcast on LAN",
"hidden: Game will not be published anywhere"],
"visibility": "public",

"_comment_credentials": "Your factorio.com login credentials. Required for games with visibility public",
"username": "redacted",
"password": "",

"_comment_token": "Authentication token. May be used instead of 'password' above.",
"token": "redacted",

"game_password": "",

"_comment_verify_user_identity": "When set to true, the server will only allow clients that have a valid Factorio.com account",
"verify_user_identity": true
}

-- this repeats --

as you can see, despite me including the username in settings.json the matchmaking server suggests it's missing when trying to create a new game "Authorization error (Missing username.)"

Fixed in 0.14.3.
