上传操作到存储后，Firebase会写入数据库

Question

我正在尝试使用作业计划程序将图像上传到firebase存储。在上传操作之后，我尝试使用上传任务的OnSuccessListener中的referece.setValue（downloadUrl）将下载URL写入firebase数据库。

我上传图片就像这样存储

        val directory = context.getDir("images", android.content.Context.MODE_PRIVATE)
        val file = File("${directory.absolutePath}/$storyKey")
        file.mkdirs()

        val fileUri = android.net.Uri.fromFile(java.io.File(file, "$imageName.jpg"))

        val task = storageReference.child(fileUri.lastPathSegment).putFile(fileUri)
        task.addOnSuccessListener { snapshot ->
            imageUploadStatus = true
            val downloadUrl = snapshot.downloadUrl
            reference.child(key).child("downloadUrl").setValue(downloadUrl)
        }.addOnFailureListener { exception ->
                    imageUploadStatus = false
                    exception.printStackTrace()
                }

但是我一直在这样崩溃
