type inside `async` block must be known in this context

Hello, I tried my best to use the crate as shown in the examples, but I struggle on an error : type inside async block must be known in this context

[dev-dependencies]
ipfs-api-backend-hyper = { version = "0.3", features = ["with-hyper-tls"] }

use ipfs_api::{IpfsApi, IpfsClient};
use ipfs_api_backend_hyper as ipfs_api;
use std::io::Cursor;

#[tokio::test]
async fn test() -> anyhow::Result<()> {
    let client = IpfsClient::default();
    let data = Cursor::new("Hello World!");

    match client.add(data).await {
        Ok(res) => println!("{}", res.hash),
        Err(e) => eprintln!("error adding file: {}", e),
    }
    Ok(())
}

error[E0698]: type inside `async` block must be known in this context

note: the type is part of the `async` block because of this `await`

  = note: multiple `impl`s satisfying `IpfsClient<_>: Default` found in the `ipfs_api_backend_hyper` crate:
          - impl Default for IpfsClient;
          - impl Default for IpfsClient<hyper_tls::client::HttpsConnector<hyper::client::connect::http::HttpConnector>>;

do you have any idea about what's going on ?
