It's very similar to this issue, but occurs in a different context.

Following minimal test code shows the behavior. The first page succeeds, the second on fails with the Type Error:

<?php

require __DIR__ . '/vendor/autoload.php';
use fivefilters\Readability\Readability;
use fivefilters\Readability\Configuration;

$readability = new Readability(new Configuration());

$content = file_get_contents('https://support.mozilla.org/en-US/kb/firefox-reader-view-clutter-free-web-pages');
$success = $readability->parse($content);

if ($success) {
    print("The mozilla.org page is fine!" . PHP_EOL);
}

$content = file_get_contents('https://www.adn40.mx/es-tendencia/2025-02-20/fin-a-las-cucarachas-la-fruta-comun-que-las-saca-de-la-cocina');
$success = $readability->parse($content);

if ($success) {
    print("The www.adn40.mx page is fine!");
}

exit($success ? 0 : 1);

Output:

The mozilla.org page is fine!
