You cannot use the `#[tokio::main]` macro when using the [[Sentry]] client. See [Async Main Function](https://docs.sentry.io/platforms/rust/#async-main-function) in their official docs for more information. If you fail to follow that as documented, it will work but it seems that traces will be messed up. ```rust fn main() { let _guard = sentry::init((" https://<your-dsn>", sentry::ClientOptions { release: sentry::release_name!(), send_default_pii: false, ..Default::default() })); tokio::runtime::Builder::new_multi_thread() .enable_all() .build() .unwrap() .block_on(async { // implementation of main }); } ```
