no process-level CryptoProvider available -- call CryptoProvider::install_default() before this point

Related to snapview/tokio-tungstenite#336

I solved it by adding rustls = ">=0.23.x" to my Cargo.toml and let _ = rustls::crypto::aws_lc_rs::default_provider().install_default(); before calling slack morphism stuff, but that doesn't seem ideal.

Hey, thanks for letting me know there are some issues.
I've removed my Cargo.lock to verify it with the latest builds (rustls v0.27.2 there) and It seems working with socket_mode example without changing anything. I would guess it is related to some specific features configuration in your app?

I think it might be when tonic v0.12.1 enables the ring feature, but I'm a bit over my head on this.

I also have multiple versions of rustls installed because aws-smithy-runtime is still on rustls v0.21.12, but that shouldn't matter.

add this code to fixed this:

rustls::crypto::ring::default_provider().install_default().expect("Failed to install rustls crypto provider");
