javascript - 创建 new File() 或 new Blob() 会导致 VSCode 扩展崩溃

Question

我目前正在尝试在 vs code webview 扩展中保存带有“另存为...”弹出窗口的文件。

我已经尝试过的事情：在 web 视图中使用 htmls“下载”属性，但链接在单击它们时什么也不做。

所以我尝试下载 nodejs https://www.npmjs.com/package/file-saver/v/1.3.2 的文件保护程序扩展，问题是，当我尝试在我的 vsCode 扩展中运行此代码时：

var file = new File(["Hello, world!"], "hello world.txt", {type:
"text/plain;charset=utf-8"}); saveAs(file);

新文件的创建导致我的 vscode 扩展崩溃：

尝试使用 msSaveOrOpenBlob 保存 blob

var blob = new Blob(["1","1"]);
window.navigator.msSaveOrOpenBlob(blob, 'msSaveBlob_testFile.docx');

当我尝试创建 blob 时导致相同的错误消息

有什么方法可以摆脱这些错误并在 vs 代码扩展中具有“另存为...”功能？
