Question

We have a website with php 8.1. It’s supposed to use exec to run highcharts-export-server to generate an svg file, but the file does not get generated:

$cmd = '/var/www/mysite/node/node_modules/lib/node_modules/highcharts-export-server/bin/cli.js --infile /tmp/node_files/nso_2024-07-10__12.50.00_77003733f89002aca7337718298f07df.json --outfile /tmp/node_files/nso_2024-07-10__12.50.00_77003733f89002aca7337718298f07df.svg';
exec($cmd, $out, $retval);

**When I run this command directly on the command line it works perfectly and the svg is created. **

$retval output:

retval: [1]

This is the output from $out:

out: [Array
(
    [0] =>     __  ___       __         __               __
    [1] =>    / / / (_)___ _/ /_  _____/ /_  ____ ______/ /______
    [2] =>   / /_/ / / __ `/ __ / ___/ __ / __ `/ ___/ __/ ___/
    [3] =>  / __  / / /_/ / / / / /__/ / / / /_/ / /  / /_(__  )
    [4] => /_/ /_/_/__, /_/ /_/___/_/ /_/__,_/_/   __/____/
    [5] =>         ____//___/                  __     _____
    [6] =>        / ____/  ______  ____  _____/ /_   / ___/___  ______   _____  _____
    [7] =>       / __/ | |/_/ __ / __ / ___/ __/   __ / _ / ___/ | / / _ / ___/
    [8] =>      / /____>  </ /_/ / /_/ / /  / /_    ___/ /  __/ /   | |/ /  __/ /
    [9] =>     /_____/_/|_/ .___/____/_/   __/   /____/___/_/    |___/___/_/
    [10] =>               /_/
    [11] =>                                                                      v3.1.1
)
]

It doesn’t go any farther than that. When I run it from the command line, I get:

    __  ___       __         __               __
   / / / (_)___ _/ /_  _____/ /_  ____ ______/ /______                    
  / /_/ / / __ `/ __ / ___/ __ / __ `/ ___/ __/ ___/                    
 / __  / / /_/ / / / / /__/ / / / /_/ / /  / /_(__  )

        ____//___/                  __     _____

I suspected it might be a permissions issue, and I changed everything in the node folder to use www-data for the user and group, but I still get the output above. There are no php (nginx) errors. Because I don’t see any errors in the node output or on the php side, I’m not sure how to proceed. I’m also not sure what the retval of 1 indicates.
