Help with phantomjs needed

frank42 · July 2, 2020, 10:06am

Hi,

I prepared all the things to make the invoice run today, but when it came to printing the invoices, I ran into a problem I don’t understand.
I didn’t realized there is a problem with my phantomjs local installation, because the tests have been done by invoice ninja via phantomjs cloud, so I didn’t notice there were problems.
No I generated 100 invoices and the pdfs are broken because of the demo key limitation, which is the reason why I now noticed that there is a problem.
Well, the problem is that the local phantomjs doesn’t seem to do its job. The builtin test page on https://my.invoiceninja.local/test_headless just states “Failed to load PDF document.”
Testing with the test.pjs on the commandline says:

root@ninja:~# phantomjs /var/www/html/invoiceninja/resources/test.pjs
\n{
“content”: “”,
“console”: []
}TypeError: Attempting to change the setter of an unconfigurable property.
TypeError: Attempting to change the setter of an unconfigurable property.
root@ninja:~#

I don’t have a clue what phantomjs wants to tell me.

But I need to get the invoices out today, so HELP PLEASE

Edit: Invoice Ninja v4.5.19, phantomjs v2.1.1, on debian 10

I’m not sure I follow, did it work for the first 100 invoices?

frank42 · July 2, 2020, 11:24am

Yes. the phantomjscloud service works. The problem is, that the local phantomjs installation doesn’t, and for obvious reasons I don’t want to rely on an external service for invoice generation.

Edit:
Perhaps I should add the error message as well…

Maybe this will help

https://docs.invoiceninja.com/configure.html#troubleshooting

frank42 · July 2, 2020, 12:57pm

Been there already, done that, didn’t help.

hillel · July 2, 2020, 4:19pm

Sorry, that’s all the info I have

frank42 · July 6, 2020, 3:53pm

Hmmm, any other info about that?
I can not imagine that there is no way in debugging this - there MUST be a way to find out why phantomjs is working fine when called on commandline but results in an unnamed error when called via invoice ninja…
It’s quite a deal breaker if I have to render all PDFs via phantomjs cloud service. Management will not allow this as a permanent solution and thus throws me back for months of work to integrate invoice ninja in our company…

Here’s the relevant code if you’d like to try to debug it.

github.com

invoiceninja/invoiceninja/blob/master/app/Libraries/CurlUtils.php

<?php

namespace App\Libraries;

use JonnyW\PhantomJs\Client;

class CurlUtils
{
    public static function post($url, $data, $headers = false)
    {
        return self::exec('POST', $url, $data, $headers);
    }

    public static function get($url, $headers = false)
    {
        return self::exec('GET', $url, null, $headers);
    }

    public static function exec($method, $url, $data, $headers = false)
    {

We’ve had a lot of issues with PhantomJS and are switching to Headless Chrome in v5.

Never heard of headless chrome, but sounds promising… however, since I can’t wait for v5 with our migration, I need a solution for phantomjs… and it’s possible that I just found one.
I know it sounds extremely strange, but I have no clue what’s different compared to yesterday, but now:

root@host:~# phantomjs /var/www/html/invoiceninja/resources/test.pjs
qt.qpa.screen: QXcbConnection: Could not connect to display

I installed phantomjs as package from phantomjs.org, and there:

root@host:~# /opt/phantomjs/bin/phantomjs /var/www/html/invoiceninja/resources/test.pjs
\n{
“contentType”: null,
“headers”: [],
“id”: 1,
“redirectURL”: null,
“stage”: “end”,
“status”: null,
“statusText”: null,
“time”: “2020-07-06T16:37:36.330Z”,
“url”: “file:///root/YOUR_LINK_HERE”,
“console”: []

The fascinating thing is, that /test_headless is working as well.

I hope it stays that way, since I have no clue how I got it working now…
