Google cloud storage uploaded via node, image is broken

Appears images uploaded using node library appear to be broken though they report the right size.

A similar issue was reported regarding using Java/PHP 

    let fileName: string = `public/static/${data["name"]}`;
    let file: Storage.File = this.bucket.file(fileName);

    var fileBuffer = Buffer.from(data["source"], 'base64');

    return from(file.save(fileBuffer, { contentType: data["contentType"], public: data["isPublic"] }))
        .pipe(map(() => {
            return { source: `${this.publicURLPrefix}/${fileName}` }
        }));

With the above code, image file is successfully upload, code converts base64 uploaded content and writes to file specified. However upon browsing to public URL the image appears corrupted/broken. Manually uploaded image works as expected.

tired solution posted here regarding node storing broken images, and it appears meta information in base64encoded image needs to be removed. Updated working code below

    let fileName: string = `${namespace}/${data["name"]}`;
    let file: Storage.File = this.bucket.file(fileName);

    //add acl, who has access to this file
    console.debug("creating/modifying file", fileName);

    let base64Source = (data["source"] as string).replace(/^data:image\/(png|gif|jpeg);base64,/,'');
    let fileBuffer = new Buffer(base64Source,'base64');

    return from(file.save(fileBuffer, { contentType: data["contentType"], public: data["isPublic"] }))
        .pipe(map(() => {
            return { source: `${this.publicURLPrefix}/${fileName}` }
        }));
