Bonjour,
je fais un serveur KTOR qui vise à permettre au joueur d'acheter/vendre des objets IG contre de l'argent IG. Pour cela, il faut que la personne puisse se connecter/enregistrer au site. Mais, comme j'utilise le pseudo Minecraft afin de faciliter le give d'item, il est impératif que le joueur s'enregistre via le serveur Minecraft. Or lorsque j'envoie ma requête, j'ai une erreur qui me dit que la réponse du serveur KTOR est vide (le body pour être précis). J'ai fait des tests et il se trouve, en effet, que le serveur ne fait rien lorsque j'envoie la requête. On peut également voir que quand le serveur KTOR reçoit la requête, il n'arrive pas à convertir le JOIN en l'objet voulu. J'ai voulu vérifier si le problème, vient du JSON avec postman or le serveur a répondu et a exécuté ma requête. Voici donc mon message d'erreur ainsi que ma méthode register et le log du serveur KTOR lorsqu'il reçoit ma requête et ici mon serveur KTOR sur GitHub.

Cliquez pour agrandir...
J'ai trouvé d'où vient le problème en réalité quand j'envoie la requête. Je ne dis pas au serveur que le contenu de la requête, c'est un JSON, donc pour ça je dois rajouter à
Java: 
HttpRequest request = HttpRequest.newBuilder(uri)
                        .POST(HttpRequest.BodyPublishers.ofString(json))
                        .header("Authorization", "Bearer " + Token.TOKEN)
                        .build();
un
Java: 
.header("Content-Type", "application/json")
ce qui donne ceci
Java: 
HttpRequest request = HttpRequest.newBuilder(uri)
.POST(HttpRequest.BodyPublishers.ofString(json))
.header("Authorization", "Bearer " + Token.TOKEN)
.header("Content-Type", "application/json")
.build();
