Não deveríamos deixar isso acontecer, eles poderiam sobrescrever um `id` que já atribuimos na base de dados. Decidir o `id` deve ser feito pelo **backend** ou pelo **banco de dados**, **não pelo cliente**.

Além disso, criamos um `secret_name` para o hero, mas até agora estamos retornando ele em todos os lugares, isso não é muito **secreto**... 😅
