O que costuma-se supor

Defining a Valid() error method on a custom claims struct in github.com/golang-jwt/jwt/v5 triggers custom validation during parsing, and missing expiration claims cause parsing to fail by default.

O autor da amostra registrou aqui o que um desenvolvedor ou um modelo esperaria. O contrato abaixo é o que de fato rodou.

Contrato

• Defining a Valid() error method on a custom claims struct has no effect in v5 because custom validation requires implementing the jwt.ClaimsValidator interface via a Validate() error method.
• Default parsing in jwt.Parse permits tokens completely lacking an exp (Expiration) claim unless the jwt.WithExpirationRequired option is explicitly passed.
