I'm not being able to connect with s3 bucket (error 403)

[lucasgooliveira]

I've been trying to use aws_sdk_s3 to connect to a bucker I've created, but I'm keep getting 403 on evey attempt,

heres my code:

pub async fn check_file_exists(
    region: String,
    directory: &str
) -> Result<bool, Box<dyn std::error::Error>> {
    let client = get_client(region).await?;
    let key = format!("{}/file.txt", directory);

    let result = client.head_object().bucket("<MY-BUCKET>").key(&key).send().await;

    match result {
        Ok(_) => Ok(true), // Object exists
        Err(e) => {
            if e.to_string().contains("NoSuchKey") {
                println!("Object does not exist");
                Err(
                    Box::new(
                        std::io::Error::new(std::io::ErrorKind::NotFound, "Object does not exist")
                    )
                )
            } else {
                println!("Failed to check object existence: {:?}", e);
                Err(
                    Box::new(
                        std::io::Error::new(
                            std::io::ErrorKind::Other,
                            "Failed to check object existence"
                        )
                    )
                )
            }
        }
    }
}

heres get_client function:

use aws_types::region::Region;
use anyhow::Result;
use aws_sdk_s3::{ Client };

pub async fn get_client(region: String) -> Result<Client> {
    let shared_config = aws_config::from_env().region(Region::new(region)).load().await;

    println!("Using region: {}", shared_config.region().unwrap());
    Ok(Client::new(&shared_config))
}

Heres my Cargo.toml

[dependencies]
aws-config = "0.56.1"
aws-sdk-s3 = "0.33.0"
tokio = { version = "1", features = ["macros"] }
anyhow = "1.0.70"
aws-types = "0.56.1"
reqwest = "0.11.22"

When I run a test :

Failed to check object existence: ServiceError { err: HeadObjectError { kind: Unhandled(Error { code: None, message: None, request_id: None, extras: {} }), meta: Error { code: None, message: None, request_id: None, extras: {} } }, raw: Response { inner: Response { status: 403, version: HTTP/1.1, headers: {"x-amz-request-id": "4MPYS86AJ1XVX247", "x-amz-id-2": "U1E9UpPFiqO7xke+EcGegUrj70+xAS2fbVicxrIuKLCF6qT7iJYRjtYEjkwMqUFh5gRStSflC+k=", "content-type": "application/xml", "date": "Sun, 15 Oct 2023 09:40:29 GMT", "server": "AmazonS3"}, body: SdkBody { inner: Once(Some(b"")), retryable: true } }, properties: SharedPropertyBag(Mutex { data: PropertyBag, poisoned: false, .. }) } }

Can you make sure you have the proper permissions to access the s3 bucket? You can that with the list-objects sample or use the AWS cli.

You can also try to run this sample if-modified-since, you are trying to use the head_object in a similar way.
