无法打开由Puppeter创建的pdf

我正在尝试使用nestjs服务器上的Puppeter从html内容（包括希伯来文字符）生成pdf。我正在使用xhr通过浏览器将输出下载到文件中，但pdf阅读器（如chrome和Adobe Acrobat Reader）无法打开该文件。联机pdf验证工具表明该文件不是pdf/不是有效的pdf

我不是pdf专家，但从pdf结构的快速查看来看，我觉得它很好。有趣的是，我尝试传递不同的htmls，大小差别很大，我看到page.pdf（）中出现了相同的缓冲区大小。我的猜测是，它指示了一些异常，但我的代码没有捕获任何内容。我怀疑这是一个大小限制，因为我的html非常小。另一件奇怪的事情是，我在容器上记录的缓冲区大小与pdf本身上与主流对象相关的第一个长度值之间存在明显的差异

怎么了
