Uncaught Twig\Error\SyntaxError: Unknown "template_from_string" function

[Chris]

{{ include(template_from_string(copyright)) }} or {% include template_from_string(copyright) %}, from Timber documentation, results in the following error:

Uncaught Twig\Error\SyntaxError: Unknown "template_from_string" function

not sure if this is because of the theme, I would expect that a code from Timber doc. would work.

Did you ever figure out why it wasn't working? Im getting the same error.

The Twig template_from_string function is not available by default. See the "Note" section in the link below.

https://twig.symfony.com/doc/3.x/functions/template_from_string.html

You can enable it in this theme by updating the existing add_to_twig function in functions.php with the following:

public function add_to_twig($twig)
{
    $twig->addExtension(new \Twig\Extension\StringLoaderExtension());
    return $twig;
}
