这里我试图将HTML转换为PDF，并使用了HTML-PDF-npm(https://www.npmjs.com/package/html-pdf))。该代码在本地运行良好，并在谷歌云运行中出现问题。

这是使用的JS代码，错误发生在pdf上。创建函数：-
var pdf = require('html-pdf');
var html = <HTML code>;
var options = {
format: 'A4',
border: {
"top": "20px",
"right": "15px",
"bottom": "15px",
"left": "12.5px"
},
};
pdf.create(html, options).toBuffer(function(err, buffer){
console.log('This is a buffer:', Buffer.isBuffer(buffer));
console.log(buffer);
看起来Cloud Run不支持HTML流，这就是我在错误消息中解释的代码，所以看起来可能不支持特定的代码。
我与NPM创建者进行了讨论，并讨论了NPM在其中使用套接字编程。因此，在进一步的研究中发现，Cloud Run不支持内部套接字调用，这就是它不起作用的正确原因。
