Getting Error `Missing required claim: exp` even when `validate_exp` is false

[LuisOsta]

pub fn verify_token(secret: String, token: String) -> Result<Claims, jsonwebtoken::errors::Error> {
    let mut validation = jsonwebtoken::Validation::new(JWT_ALGORITHM);
    validation.validate_exp = false;
    let data = jsonwebtoken::decode::<Claims>(
        &token,
        &jsonwebtoken::DecodingKey::from_secret(secret.as_bytes()),
        &validation,
    )?;

    Ok(data.claims)
}

This is the way that I'm using the jsonwebtoken library where the Claims struct is

#[derive(Debug, serde::Serialize, serde::Deserialize)]
pub struct Claims {
    pub sub: String,
    pub name: String,
}

I saw https://github.com/Keats/jsonwebtoken/issues/239. But why not have it also not care if its absent/present if validate_exp is set to false?

Presence/absence and validation are two different things. You might want to enforce having an exp field but not want to validate it with the crate because you're not using the standard timestamp for example.
