Hello!

Je suis pas un programmeur donc je peux avoir une mauvaise terminologie ou une mauvaise compréhension. Mais un blocking call en soit n'est pas nécessairement un problème. C'est simplement que la fonction n'est pas asynchrone donc doit être terminée avant qu'une autre ait lieu. L'erreur est présente depuis la migration vers GraphQL chez Hilo, c'est probablement un easy fix mais comme ça ne brise rien et que je suis plutôt lâche (et que j'ai repris ce truc bénévolement sur mon temps personnel) je m'y suis pas vraiment attardé.

Je peux regarder si je peux régler.
