Deserialisation failing from osu lazer api?

[Dcs1729]

Hi, I apologise in advance if I've made a mistake and this is something on my end.

The wrapper seems to be failing to deserialise responses from the lazer api as of the last day or so. I haven't changed my code at all so I suspect a change may have been made to the lazer resposne format?

I'm currently getting an error upon running this function

pub async fn get_recent_score(osu: &Osu, user_id: impl Into<UserId>, index: usize, include_fails: bool) -> Option<Score> {
    let res = osu
        .user_scores(user_id)
        .recent()
        .mode(GameMode::Osu)
        .include_fails(include_fails)
        .offset(index)
        .limit(1)
        .await;

    match res {
        Err(OsuError::NotFound) => None,
        Err(e) => panic!("failed to get recent score: {}", e),
        Ok(scores) => {
            scores.first().cloned()
        }
    }
}

Which gives me a Parsing Varianet of the OsuError e.g. running this on my own user ID gives:

I'm using this line in my Cargo.toml: rosu-v2-lazer = {package="rosu-v2", git = "https://github.com/MaxOhn/rosu-v2", branch = "lazer", features = ["replay"] }

Apologies again if I've made a mistake, otherwise I'd be happy to help if you need any other information to help solve the issue.

Indeed they added a new field to scores just recently which isn't a problem in of itself but the deserialization is currently configured to be extra sensitive to make sure no change goes unnoticed.

I''ve already pushed a fix so I believe a simple cargo update -p rosu-v2 should do the trick for you.

Ah, thank you! I appreciate the info.
