Se ele não ver o header de `Autorização` ou o valor não tem um token `Bearer`, vai responder com um código de erro  401 (`UNAUTHORIZED`) diretamente.

Você nem precisa verificar se o token existe para retornar um erro. Você pode ter certeza de que se a sua função for executada, ela terá um `str` nesse token.
