Hi Vincent,
You’re trying to configure core routers so you need to put your configuration in the main router file (src/api/post/routes/post.ts) and declare your policy here.
import { factories } from "@strapi/strapi";
export default factories.createCoreRouter("api::post.post", {
config: {
delete: {
policies: ["user-post-policy"],
},
update: {
policies: ["user-post-policy"],
},
},
only: null,
});
