Description

I tried this code with opentelemetry v0.21.0:

opentelemetry = { version = "0.21.0" }
opentelemetry_sdk = { version = "0.21.0", features = ["rt-tokio"] }
opentelemetry-aws = "0.9.0"
opentelemetry-otlp = { version = "0.14.0", features = ["grpc-tonic", "tls"] }
tracing-opentelemetry = "0.22.0"

use opentelemetry_sdk::trace::TracerProvider;
use tracing_subscriber::prelude::*;
use tracing_subscriber::{fmt, fmt::format, EnvFilter};

pub fn init_observability() -> Result<(), Error> {
    let exporter = opentelemetry_otlp::new_exporter()
        .tonic()
        .build_span_exporter()?;
    // Create a new OpenTelemetry trace pipeline that prints to stdout
    let provider = TracerProvider::builder()
        .with_simple_exporter(exporter)
        .build();
    let tracer = provider.tracer("readme_example");
    let fmt_layer = fmt::layer().event_format(format().json());
    let filter_layer = EnvFilter::from_default_env();
    let telemetry_layer = tracing_opentelemetry::layer().with_tracer(tracer);

    let subscriber = tracing_subscriber::registry()
        .with(filter_layer)
        .with(fmt_layer)
        .with(telemetry_layer);
    tracing::subscriber::set_global_default(subscriber)?;
    Ok(())
}

When using opentelemetry v0.21.0, rustc raises no error.

However, if using opentelemetry v0.22.0 rustc raises the following error.

tracing = { version = "0.1.40", features = ["log","attributes"] }
tracing-subscriber = { version = "0.3.18", features = ["std", "env-filter","json"] }
opentelemetry = { version = "0.22.0" }
opentelemetry_sdk = { version = "0.22.0", features = ["rt-tokio"] }
opentelemetry-aws = "0.10.0"
opentelemetry-otlp = { version = "0.15.0", features = ["grpc-tonic", "tls"] }
tracing-opentelemetry = "0.22.0"

#100 will fix this

Thank you. I checked tracing-opentelemetry v0.23.0 and succeeded to upgrade to opentelemetry v0.22.
