An await doesn't wait the end and return of a function about asyncawait HOT 2 CLOSED

Hi @Kaos1337,

The downloadFile() function is not awaitable in its current form. Try this:

function downloadFile(uri, filename) {
    return new Promise(function (resolve, reject) {
        console.log("[downloadFile] definitiveName: " + filename); <--- print correctly the definitive name
        request(uri)
        .pipe(fs.createWriteStream(filesFolder + filename))
        .on('close', function(err) {
            if(err) {
                reject(err);
            }
            else {
                console.log("[downloadFile] Downloaded: " + filename); <--- print correctly the definitive name
                resolve(filename); <-- the return of the function
            }
        });
    });
}

Explanation: The original downloadFile() function runs the first console.log, then starts the asynchronous request(uri) operation, then immiediately returns undefined. This undefined is what is being passed to await in the other function you provided. I have wrapped the code inside downloadFile in a promise, and returned the promise. The promise gets resolved once the file is downloaded. await receives this promise and waits for it to resolve before continuing.

BTW wrap your code in triple backticks to make it easier to read in github comments, like so:

```
function foo() { ... }
```

Thank you, works!
I've also corrected my first message as you suggested.
