Issue with Bamboo Twig

[sinyayadynya]

Hi, I want to use Bamboo Twig (https://www.drupal.org/project/bamboo_twig), but after creating the following 'components/_twig-components/functions/pl_bamboo_load_currentuser.function.php' file with:

<?php
/**
 * @file
 * Add "bamboo_load_currentuser" function for Pattern Lab.
 */

$function = new Twig_SimpleFunction('bamboo_load_currentuser', function ($string) {
  return $string;
});

I'm getting the following error while doing 'yarn start':

PHP Warning:  Invalid argument supplied for foreach() in ../web/themes/custom/rw/components/_twig-components/functions/add_attributes.function.php on line 61

Error with code 255 after running: php pattern-lab/core/console --generate

Any idea how to solve it?

Thanks for help.
