[ Bug ] Failed to get information for summoner=

[pepinocada]

Describe the bug
I start a custom game (without spectator delay) on EUNE and add my friends. Then I trigger lobby synchronization, champ select, and end of game. Next, I enable InGame synchronization in the Observer tool. I start the game from the lobby in the client, and I’m set as a spectator. Champ select starts; the toolkit console correctly reports "Champselect - active," followed by "Champselect - game started." Then the WebAPI attempts to retrieve data about one of the players—even though the player is in the game, it returns an empty string. As a result, the InGame HUD crashes and fails to load.

To Reproduce

1. Start the lobby, invite at least 1 summoner, switch yourself as a spectator.
2. Sync Lobby, Champselect and InGame in Observer.
3. Start the champ select, pick champs and let the game start.
4. You will get the error.

Expected behavior
I would expect the game data to be retrieved correctly after collecting data on one of the players and the InGame UI loads.
