Can't get snappdf to work - 500 error

Self-Hosted | v5
1

v5 installed and running for a while now, with root access. But I was using PhantomJS and want to switch to snappdf. Getting a 500 error when trying to view/generate an invoice.

@david @ben any suggestions?

Drop to the command line and run

vendor/bin/snappdf convert --html="<html</html>" g.pdf

This will confirm snap is working by producing an empty pdf

looks like … chrome is not installed?

root@vps1:/home/invoices/webapps/invoices# ./vendor/bin/snappdf convert --html="<html" g.pdf

In Snappdf.php line 223:

tried this, no luck:

root@vps1:/home/invoices/webapps/invoices# ./vendor/bin/snappdf download
Chromium binary already downloaded. Provide --force to download again.

@torch2k

Your missing some subsystem packages, have a look here for your flavour of linux:

Thank you. Packages are now installed, and I was able to generate a “g.pdf” as you requested. However, Invoice Ninja is still throwing a 500 error:

Could be a permissions error now, you may want to check the webuser can write to public/storage

@david I have a couple of new bits of info here.

  1. my server is intended to have files and folders set to 644/755 permissions, respectively. InvoiceNinja wants to use 664/775 by default. I adjusted all permissions under /public/ and also adjusted /config/filesystems.php to match. This didn’t solve anything…

  2. laravel.log states:

    [2021-07-29 12:45:02] production.ERROR: File not found at path: 9og9ratdqgqn6l9kww3ct7p4ejy9kw6k/m243i3Cbm4Byak1nhje0NbyStq13tslnO7Oijrwe/isec80ccoc8nxaed9usmixq6mawhj1kx/invoices/2021-4414.pdf

However, when I navigate to ./public/storage/9og9ratdqgqn6l9kww3ct7p4ejy9kw6k/m243i3Cbm4Byak1nhje0NbyStq13tslnO7Oijrwe/isec80ccoc8nxaed9usmixq6mawhj1kx/invoices/, the invoice PDF is actually there.

Is there an issue with snappdf / ninja not using /public/storage/ in it’s path somehow?

from my /config/filesystems.php:

    'public' => [
        'driver' => 'local',
        'root' => public_path('storage'),
        //'root' => 'storage/',
        // 'root' => storage_path('app/public'),
        'url' => env('APP_URL').'/storage',
        'visibility' => 'public',
        'permissions' => [
            'file' => [
                'public' => 0644,
                'private' => 0600,
            ],
            'dir' => [
                'public' => 0755,
                'private' => 0700,
            ],
        ],
    ],

You may need to appen /publc to your APP_URL
