Keycloak dit 403 interdit pour les méthodes HTTP autres que GET

Je configure une instance Keycloak pour qu'elle fonctionne avec l'application Spring Boot avec la sécurité Spring incluse. J'utilise postman pour tester le service. Je commence par obtenir un nouveau jeton d'accès et cela fonctionne bien. Lorsque je fais un appel HTTP GET au point de terminaison sécurisé - tout se passe bien, le personnel est renvoyé. Mais lorsque je fais un appel HTTP POST / PUT / DELETE au point de terminaison sécurisé Keycloak dit Erreur 403 Interdit. Jetez un œil et dites-moi ce qui ne va pas.

J'ai déjà testé l'option http.csrf (). disable (), puis fonctionne correctement, mais ce n'est pas la solution pour la production.
