Voilà... je crois que le problème vient d'une commande que j'ai réalisé dans un commande bloc (je tentais de faire apparaître une tête que j'avais personnalisé .Dans le message d'erreur je retrouve la même commande que j'avais écrite pour faire apparaître la tête, elle se trouve dans la partie "Item being rendered"
J'espère que ça t'aidera à résoudre mon problème
Tchüss !
