Hi, I noticed that filter function doesn't work when applied to serverside datatable. It works well when serverside is turned off or applied to other charts. Here's the code:

$dataSource = function() {
            return $this->src($this->params['database'])
            ->query($this->params['query_input'])
             ->pipeIf(!empty($this->params['filters']), function($node) {
                $filters = $this->params['filters'];
                $convertedFilters = [];
                for ($i = 0; $i < sizeof($filters['filter_field']); $i++) { 
                    $convertedFilters[] = [$filters['filter_field'][$i], $filters['filter_operator'][$i], $filters['filter_value'][$i]];
                }
                return $node->pipe(new Filter($convertedFilters));
            })
};

Still doesn't work.

$dataSource = function($scope) {
            return $this->src($scope['database'])
            ->query($scope['query_input'])
            ->pipeIf(!empty($scope['filter']), function($node) {
              $filters = $scope['filters'];
              $convertedFilters = [];
              for ($i = 0; $i < sizeof($filters['filter_field']); $i++) { 
                  $convertedFilters[] = [$filters['filter_field'][$i], $filters['filter_operator'][$i], $filters['filter_value'][$i]];
              }
              return $node->pipe(new Filter($convertedFilters));
            });
          };

Datatables::create([
          'name' => 'uniqueTable',
          'Title' => $this->params['title'],
          'scope' => $this->params,
          'dataSource' => $dataSource,
          'columns' => $columns,
          'options' => 
          [
            'searching' => $searching, 
            'colReorder' => true, 
            'paging' => $paging
          ],
          'serverSide' => $serverSide,
          'cssClass' => $cssClass
        ]);
