Problem/Motivation

There are two problems here, both of them in Drupal\Core\Config\Entity\Query\Condition.php.

This occurs under the condition that there are array values stored for a property in a config entity. In order to match the comparison correctly, the entity query system needs modification.

  1. There's a conversion to lower case that fails since it can't take an array as input.
  2. There's no comparison of a single value against an array value. The opposite exists, there a comparison with $condition['value'], but it matches the opposite, comparing an array in the condition with a mixed value in entity config.

The error given is:
TypeError: mb_strtolower(): Argument #1 ($string) must be of type string, array given in mb_strtolower() (line 174 of core/lib/Drupal/Core/Config/Entity/Query/Condition.php). Drupal\Core\Config\Entity\Query\Condition->match(Array, Array) (Line: 145)

Steps to reproduce

  1. Install webform and import the sample form attached, notice there are two categories present in the config.
  2. Set up a module that extracts entities from webform, filtered by the presence of a category. Sample code is given below.

Comparison code:

    $webforms = \Drupal::entityQuery('webform')
      ->accessCheck(FALSE)
      ->condition('categories', 'sample_category_1')
      ->execute();

Proposed resolution

When there's a match against the array value in entity config, the entityQuery should return all matching entities.
