Specified cast is not valid.

Hi, I'm trying to download an image from the URL but it gives me the "Specified cast is not valid" error. Here is my code please correct me on what I'm doing wrong:

public void DownloadImage(string fileUrl, string name)
    {

        RestClient.Get(new RequestHelper {
            Uri = fileUrl,
            // DownloadHandler = new DownloadHandlerFile(imagePath + filename),
            Method = "GET",
            DefaultContentType = true,
            EnableDebug = true,
        }).Then(res =>
        {
            Texture2D tex = ((DownloadHandlerTexture) res.Request.downloadHandler).texture;

            Sprite sprite = Sprite.Create(tex, new Rect(0, 0, tex.width, tex.height), new Vector2(tex.width / 2, tex.height / 2));
            if (img != null)
            {
                img.overrideSprite = sprite;
                img.preserveAspect = true;
            }

        }).Catch(err => {
            Debug.Log(err.Message);
            Debug.Log("url: " + fileUrl);
        });
    }

Found solution:

public void DownloadImage(string fileUrl, string name)
    {

        RestClient.Get(new RequestHelper {
            Uri = fileUrl,
            DownloadHandler = new DownloadHandlerTexture(true),
            Method = "GET",
            DefaultContentType = true,
            EnableDebug = true,
        }).Then(res =>
        {
            Texture2D tex = ((DownloadHandlerTexture) res.Request.downloadHandler).texture;

            Sprite sprite = Sprite.Create(tex, new Rect(0, 0, tex.width, tex.height), new Vector2(tex.width / 2, tex.height / 2));
            if (img != null)
            {
                img.overrideSprite = sprite;
                img.preserveAspect = true;
            }

        }).Catch(err => {
            Debug.Log(err.Message);
            Debug.Log("url: " + fileUrl);
        });
    }
