错误：使用html-pdf NPM时在Cloud Run上编写EPIPE

问题描述

在这里，我尝试将HTML转换为PDF，并使用html-pdf npm（https://www.npmjs.com/package/html-pdf）。该代码在本地运行良好，并在Google Cloud Run上出现问题。

Error: write EPIPE at afterWriteDispatched (internal/stream_base_commons.js:154:25) at writeGeneric (internal/stream_base_commons.js:145:3) at Socket._writeGeneric (net.js:786:11) at Socket._write (net.js:798:8) at doWrite (_stream_writable.js:403:12) at writeOrBuffer (_stream_writable.js:387:5) at Socket.Writable.write (_stream_writable.js:318:11) at PDF.PdfExec [as exec] (/usr/src/app/node_modules/html-pdf/lib/pdf.js:141:15) at PDF.PdfToBuffer [as toBuffer] (/usr/src/app/node_modules/html-pdf/lib/pdf.js:44:8) at utilities.createPDF (/usr/src/app/routes/lib/utilities.js:810:31)

 at Socket._write (net.js:798:8) {

 errno: 'EPIPE',code: 'EPIPE',syscall: 'write'

这是使用的JS代码，在 pdf.create 函数上发生了错误：-

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);

解决方法

看起来像Cloud Run does not support HTML streaming，这就是我解释错误消息中要执行的代码的原因，因此似乎不支持特定代码。

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的情况。因此，在进一步研究中发现，Cloud Run不支持内部Socket调用，这是不起作用的正确原因。
