Brosershot PDF not loading external images and styles when run on a queue

Problem

I have an issue with generating PDFs via Browsershot on a queue. The PDFs do not load any images or stylesheets for some reason however, when generating the same PDF via a browser request the images and stylesheets are loaded as expected.

I suspect the issue is related to the paths used for the images and styles, but I'm not sure beyond that.

The first image shows the expected output, and the second shows what the actual output looks like. Here is the expected output when generated via a web request.

This is the actual output when generated from a queue.

Tried so far

Browsershot code

$content = view('site-report.cover-template', ['site' => $this->site])->render();

Browsershot::html($content)
  ->waitUntilNetworkIdle()
  ->noSandbox()
  ->ignoreHttpsErrors()
  ->setNodeBinary('/usr/bin/node')
  ->setNpmBinary('/usr/bin/npm')
  ->margins(0, 2, 0, 2)
  ->format('A4')
  ->noSandbox()
  ->setOption('args', ['--disable-web-security'])
  ->showBackground()
  ->waitUntilNetworkIdle()
  ->save($targetFullPath);

PDF Blade layout

<head>
    <meta charset="utf-8">
    <meta name="viewport" content="width=device-width, initial-scale=1">
    <meta name="csrf-token" content="{{ csrf_token() }}">

    <title>{{ config('app.name', 'Laravel') }}</title>

    <!-- Scripts -->

redirect_stderr=true

Any help would be much appreciated!

Solution

  • I had a similar issue with devfactory/imagecache.

    In my case, it was because database queues run from the Laravel root "/" path, and the website (and sync queues) run from the Laravel public path "/public".

    I created a github issue (that was closed with no fix). https://github.com/laravel/framework/issues/45679

    My solution was to add the following to all my jobs:

    if(config('queue.default') == "database" && !str_ends_with(getcwd(), 'public')) { chdir('public'); }
