This version is not compatible with Laravel 11. (see https://laravel.com/docs/11.x/upgrade#doctrine-dbal-removal). All concentred on class SchemaUtils.php.

A small compatible fixture is :

Thanks for your quick fix but the same error happen in firstHumanReadableField() still.

Your code don't working with me... try

public static function firstHumanReadableField(string $table, string $key = null) {
       $all = self::getTableFields($table);
       if (empty($all)) return null;

       $last = null;
       foreach ($all as $f) {
           if (preg_match('/_id$/', $f['id'])) continue;
           if (preg_match('/(string|text)/', $f['type'])) {
               return $key && isset($f[$key]) ? $f[$key] : $f;
           }
           $last = $f;  
       }

       $result = $last ?? $all[0];
       return is_array($result) && $key && isset($result[$key]) ? $result[$key] : $result;
   }
