Cannot join mount namespace of pid 1: Operation not permitted

I have simple puppeteer script in nodejs like below

const puppeteer = require("puppeteer");

(async () => {
  const browser = await puppeteer.launch({
    headless: true,
    executablePath: "/snap/bin/chromium",
    args: ["--no-sandbox", "--disable-setuid-sandbox"],
  });

  const page = await browser.newPage();

  await page.goto("https://google.com");
  //get screenshot
  await page.screenshot({ path: "app4test.png" });
})();

when i ssh to my user and run node script.js , its working fine

When i do that via forever in ssh .. forever script.js , its working fine..

but when i do via php ,

<?php
// Define the command
$command = "forever start /home/example.com/app4test.js";

// Execute the command
$output = exec($command);

// Output the result
echo "<pre>$output</pre>";
?>

I get below error
