Problem/Motivation
I have to remove the Warning: Undefined array key 0 en Drupal\Core\Database\Query\Condition->condition() (línea 116 de /var/www/html/web/core/lib/Drupal/Core/Database/Query/Condition.php)
Steps to reproduce
you may install Drupal 10.4.1
Proposed resolution
In the line 116 add a if
if(isset($value[0])){
$value = $value[0];
}
Instead of this
$value = $value[0];
