Thats not true, that player exists in your database. In fact, player_id was present at some time, and later turned to null.

Thats an issue for us, because we’ve translated all player names to different language and we’re unable to use our translation if player_id is absent.

Hello, when a player has a {player_id} : NULL in events or lineups, it’s because we don’t have his information in our database.
