What the simplest way to get object from s3?

I'm trying, but I'm getting the this message: Promise { pending }

class S3Utils {
    static getFile(params) {
        return new Promise(function(resolve, reject) {
            s3.getObject(params, (err, data) => {
                if (!err) {
                    resolve(data);
                } else {
                    reject(err);
                }
            });
        });
    }
}

let file = S3Utils.getFile(params);

Async function always returns promise `let file = await S3Utils.getFile(params);` – bato3 Mar 19 '19 at 16:32

@bato3 then he will get `undefined` as result – ponury-kostek Mar 19 '19 at 16:33
thanks @ponury-kostek, also `return await s3.getObject(params,` – bato3 Mar 19 '19 at 16:34
@bato3 this change nothing, still `undefined` – ponury-kostek Mar 19 '19 at 16:35

You need to wrap `s3.getObject` with `Promise` and use `resolve` instead of `return`, and there is no need to use `async/await` – ponury-kostek Mar 19 '19 at 16:36
Nooo!!!!1111 one one one.... This is an extremely "interesting" code. I did not notice so many things. There is also no `then` there XD – bato3 Mar 19 '19 at 16:39
