No data returned error in Core php

[techsamy]

Hello,

I am usng Php-chrome-html2pdf in core php but it displaying me the error

Fatal error: Uncaught Spiritix\Html2Pdf\ConverterException: No data returned in C:\Inetpub\vhosts\abc.com\xyz.co.in\vendor\spiritix\php-chrome-html2pdf\src\Spiritix\Html2Pdf\Converter.php:196 Stack trace: #0 C:\Inetpub\vhosts\abc.com\xyz.co.in\convert.php(24): Spiritix\Html2Pdf\Converter->convert() #1 {main} thrown in C:\Inetpub\vhosts\abc.com\xyz.co.in\vendor\spiritix\php-chrome-html2pdf\src\Spiritix\Html2Pdf\Converter.php on line 196

It working fine on xampp localhost but when i am trying to upload this on my web server it giving me the above error.

Here is my Code.

`<?php ini_set( 'display_errors', 1 ); error_reporting( E_ALL );

require_once DIR . '/vendor/autoload.php';

use Spiritix\Html2Pdf\Converter; use Spiritix\Html2Pdf\Input\UrlInput; use Spiritix\Html2Pdf\Output\DownloadOutput;

$input = new UrlInput();

$input->setUrl('https://www.google.com/');

$converter = new Converter($input, new DownloadOutput());

$converter->setOption('landscape', false);

$converter->setOptions([ 'printBackground' => true, 'headerTemplate' => '

I am a header

', ]); $output = $converter->convert(); $filename=date('YmdHis').".pdf"; $output->download($filename,'D'); ?>`

This error means that the node executable didn't return any output. As a next step, I'd suggest debugging it by adding var_dump($command); to src/Spiritix/Html2Pdf/Converter.php on line 213. Then run the script, copy the command and run it manually on the webserver. Then report back here what output you've got or if there were any errors.

After using var_dump($command) , it shows the below error.

I am a header<\\/p>""}"" Fatal error: Uncaught Spiritix\Html2Pdf\ConverterException: No data returned in C:\Inetpub\vhosts\arcclients.com\xyz.co.in\vendor\spiritix\php-chrome-html2pdf\src\Spiritix\Html2Pdf\Converter.php:196 Stack trace: #0 C:\Inetpub\vhosts\arcclients.com\xyz.co.in\convert.php(25): Spiritix\Html2Pdf\Converter->convert() #1 {main} thrown in C:\Inetpub\vhosts\arcclients.com\xyz.co.in\vendor\spiritix\php-chrome-html2pdf\src\Spiritix\Html2Pdf\Converter.php on line 196 string(225) "node C:\Inetpub\vhosts\arcclients.com\xyz.co.in\vendor\spiritix\php-chrome-html2pdf\src\Spiritix\Html2Pdf\..\..\..\index -o "{""landscape"":false,""printBackground"":true,""headerTemplate"":""

And what do you get if you execute the following command manually in your terminal?

node C:\Inetpub\vhosts\arcclients.com\xyz.co.in\vendor\spiritix\php-chrome-html2pdf\src\Spiritix\Html2Pdf\..\..\..\index -o "{""landscape"":false,""printBackground"":true,""headerTemplate"":""I am a header<\\/p>""}"

After Executing the following command in terminal we get the following Error : node C:\Inetpub\vhosts\arcclients.com\binaykumar.co.in\vendor\spiritix\php-chrome-html2pdf\src\Spiritix\Html2Pdf\..\..\..\index -o "{""landscape"":false,""printBackground"":true,""headerTemplate"":""I am a header<\\/p>""}"

That looks like PDF data is being returned, so the actual converter works fine. Must be related to your web server settings then. You will need to debug the Converter.php class which is responsible for retrieving the output from Node, cannot provide assistance here, sorry.

I had the same problem. In my case 195 string - "if (mb_strlen($result['output']) === 0) {" equal true, but output was not empty. php8.1-mbstring extension was not installed. I ran "sudo apt install php8.1-mbstring" and problem solved!

Had the same issue and turns out same as @dss1210 the mbstring module wasn't installed. So odd that there'd be no error calling the function without the module installed.
