错误消息显示“存储/未找到对象”和“对象'k91a73uzb99'不存在”。这意味着您要使用以下代码行上传文件：

this.ref = this.firesStore.ref(id);
this.task = this.ref.put(event.target.files[0]);

尚未完成上传。您尝试在上传完成之前获取其下载URL：

this.newUrl = await this.firesStore.ref(id).getDownloadURL();

您将要遵循使用返回的AngularFireUploadTask的example code from the documentation来等待上载完成，然后再访问其下载URL。因此，它将如下所示：

this.uploadPercent = task.percentageChanges();
// get notified when the download URL is available
task.snapshotChanges().pipe(
    finalize(() => this.newUrl = this.ref.getDownloadURL() )
 )
.subscribe()

如何使用getDownloadURL（）（带有令牌）获取完整的URL？
