workers-rs: Unable to get local issuer certificate

I'm attempting to use the reqwest library within my worker to contact a third-party api.

async fn test_reqwest() -> Result<String> {
    let resp = reqwest::get("https://workers.cloudflare.com").await.unwrap().await.unwrap();
    Ok(String::from(resp))
}

I am running the worker using wrangler dev
When the request is made wrangler shows the following error:

workerd/jsg/util.c++:275: error: e = kj/compat/tls.c++:221: failed: TLS peer's certificate is not trusted; reason = unable to get local issuer certificate

The same happens if I use workers Fetch api:

async fn test_reqwest() -> Result<String> {
    let mut resp = Fetch::Url("https://httpbin.org/anything".parse().unwrap())
        .send()
        .await?;
    let txt = resp.text().await?;
    Ok(String::from(txt))
}


Is there a feature / configuration change I need to make to allow the worker to access third party apis?

Thank you.
