Javascript错误处理异步功能

Question

我目前有两个包含promise的函数：

function getLyrics(url) {
    youtubedl.getInfo(url, function (err, info) {
        // handle errors here
        if (err) {
            console.log(err);
            throw "Error retrieving lyrics (youtube-dl)";
        } else {
            var fields = info.title.split('-');
            var artist = sanitizeArtistOrTitle(fields[0].trim());
            // TODO: handle possibility of - in artist/song name
            var title = sanitizeArtistOrTitle(fields[1].trim());


            const options = {
                apiKey: geniusKey,
                title: title,
                artist: artist,
                optimizeQuery: true
            };

            geniusSong(options).then(function (result) {
                urlFields = result.url.split('/');
                // check if the name of the song and artist are in the url 
                // since the api seems to return a random lyric page
                // when the actual page cannot be found
                var titleAndArtist = urlFields[3].split('-').join(' ').toLowerCase();
                if (titleAndArtist.includes(artist.toLowerCase()) &&
                    titleAndArtist.includes(title.toLowerCase())) {
                    // get the lyrics and write to a file
                    writeLyrics(options);
                } else {
                    throw "Lyrics page does not match the song details"
                }

            }).catch(function (err) {
                console.log(err);
                throw "wtf going on";
            })
        }
    })
}

function writeLyrics(options) {
    geniusLyrics(options)
        .then(lyrics => sanitizeLyrics(lyrics))
        .then(sanitizedLyrics => fsPromise.writeFile("../aux_files/words.txt",
            sanitizedLyrics.toString()))
        .then(console.log("written to file"))
        .catch(function (err) {
            console.log(err);
            throw "Could not lyrics to file";
        });
}

首先，我在writeLyrics中呼叫getLyrics的方式安全吗？我应该使用异步/等待吗？接下来，我正在使用express.js，我想在中间件函数中调用getLyrics并捕获任何错误。 try / catch块不起作用，那么我应该怎么做？
