        // Save first item to get keys to display at header
        if (is_null($this->firstItem)) {
            $this->firstItem = $item;
        }

        $this->table->addRow($item);
    }

    /**
     * {@inheritdoc}
     */
    public function finish() {
        $headers = $this->firstItem ? array_keys($this->firstItem) : [];
        $this->table->setHeaders($headers);
        $this->table->render();

        $this->firstItem = null;

It seems like null of type null is incompatible with the declared type array of property $firstItem.

    }
