laravel-medialibrary: SQL Error when getMedia()

Hello. I’m having this SQL error when I try to get the media from my model.

>>> $user = App\Models\User::find(301);
=> App\Models\User {#834
     id: "301",
     username: "username",
     email: "email@domain.lo",
     first_name: "Jon",
     last_name: "Snow",
     birthday: null,
