Android Picasso图像加载失败，并显示错误

Question

我正在尝试使用毕加索从mp3提取图像并将其加载到imageview，但是我无法做到这一点，每次调用毕加索的OnError方法时，我都无法确定问题所在帮助将不胜感激。

 val file = File("/storage/emulated/0/UCDownloads/04 - Bom Diggy Diggy - DownloadMing.SE.mp3")
        Picasso.get()
                .load(file)
                .resize(50, 50)
                .into(holder.covimg,object:Callback{
                    override fun onSuccess() {
                        TODO("not implemented") //To change body of created functions use File | Settings | File Templates.
                    }

                    override fun onError(e:Exception) {
                        e.printStackTrace()
                    }
                })

这是我在logcat中遇到的错误：
