Rust: поток паникует при запуске внутри iframe, но не на обычной вкладке браузера

Я играю с созданием приложения на Zendesk с использованием Rust. Ниже показана функция ржавчины на стороне сервера, которая вызывается в маршруте

pub fn oktaredirectprocessor(mut cookies: Cookies, code: String, state: String) -> bool {
    let cookie_state_string = cookies.get_private("state").unwrap().value().to_string();
    println!("cookie retrieved in oktaredirectprocessor is {}", cookie_state_string);
    if state != cookie_state_string {
        debug!("State did not match");
        false
    }else if code == ""{
        debug!("Code is empty");
        false
    }else{
        let oktarequest: Oktarequest = Oktarequest::new();
        let http = reqwest::Client::new();
        let config = oidc::discovery::discover(&http, oktarequest.issuer).expect("error in config-discovery-oidc");
        let jwks = oidc::discovery::jwks(&http, config.jwks_uri.clone()).expect("error in jwks-discovery-oidc");
        let provider = oidc::discovery::Discovered(config);
        let client = oidc::Client::new(oktarequest.id, oktarequest.secret, oktarequest.redirect, provider, jwks);
        let mut token = client.request_token(&http, code.as_str()).expect("error in request token-oidc");
        client.decode_token(&mut token.id_token).expect("error in decode token oidc");
        client.validate_token(&token.id_token, Some(cookies.get_private("nonce").unwrap().value()), None).expect("error in validate token oidc");               cookies.add_private(Cookie::new("access_token", token.access_token().to_string()));
        true
    }

}

Это работает, когда я запускаю localhost прямо с вкладки браузера. Однако поток паникует, если я запускаю приложение из Zendesk. Ниже приведена обратная связь. Я начинающий кодер и не совсем понимаю.

Как ни странно, проблематичный "cookies.get_private("state").unwrap()" работает в другой функции даже при запуске внутри Zendesk. Ниже приведена функция, где она работает

fn oktalogin(mut cookies: Cookies) -> Redirect {
    let oktarequest: Oktarequest = Oktarequest::new();
    cookies.add_private(Cookie::new("state", oktarequest.state.clone()));
    cookies.add_private(Cookie::new("nonce", oktarequest.nonce.clone()));
    println!("stored state cookie from random gen is: {}", cookies.get_private("state").unwrap().value().to_string());
    let http = reqwest::Client::new();
    let config = oidc::discovery::discover(&http, oktarequest.issuer).expect("error in config-discovery-oidc");
    let jwks = oidc::discovery::jwks(&http, config.jwks_uri.clone()).expect("error in jwks-discovery-oidc");
    let provider = oidc::discovery::Discovered(config);
    let client = oidc::Client::new(oktarequest.id, oktarequest.secret, oktarequest.redirect, provider, jwks);
    let options = Options{
        scope: Some("openid profile email".to_string()),
        state: Some(oktarequest.state.clone()),
        nonce: Some(oktarequest.nonce.clone()),
        ..Default::default()
        };
    let auth_url = client.auth_url(&options);
    Redirect::to(auth_url.into_string())
}
