To Reproduce
test code like this

 #[tokio::test]
    async fn upload_file() {
        let region = Region::Custom {
            region: "".into(),
            endpoint: ENDPOINT.to_string(),
        };

        let credentials = Credentials::new(
            Some(&ACCESS_KEY.to_string()),
            Some(&SECRET_KEY.to_string()),
            None,
            None,
            None,
        )
        .unwrap();

        let mut bucket = Bucket::new(&BUCKET_NAME.to_string(), region, credentials)
            .unwrap()
            .with_path_style();

        let path = "test.txt";
        let content = Bytes::from_static(b"test content");
        let response_data = bucket.put_object(path, content.chunk()).await.unwrap();

        assert_eq!(response_data.status_code(), 200);

        let resp = bucket.get_object("test.txt").await.unwrap();
        assert_eq!(resp.status_code(), 200);

        let resp = bucket.delete_object("test.txt").await.unwrap();
        assert_eq!(resp.status_code(), 200);
    }

@maojinhua, can't really be sure, DELETE has a pretty good test coverage, so I'd expect it to work. Not sure where you're running this, but a "" region will likely cause problems...
