I am trying to create an install script to overwrite some bluefoot configurations. I am trying to figure out what is in the $ buttonItemBlock variable so that I can pass that to another class. However I can not get anything to print during upgrade in the console.

<?php  namespace vender\module\Setup;  use Gene\BlueFoot\Model\Installer\File as InstallerFile; use Magento\Framework\Filesystem\Io\File as IoFile; use Magento\Framework\Module\Dir\Reader; use Magento\Framework\Setup\InstallDataInterface; use Magento\Framework\Setup\ModuleContextInterface; use Magento\Framework\Setup\ModuleDataSetupInterface; use Gene\BlueFoot\Model\Attribute\ContentBlockRepository;  /**  * Class to install data for list builder BlueFoot block  */ class InstallData implements InstallDataInterface {     /**      * @var Reader      */     protected $  moduleReader;      /**      * @var IoFile      */     protected $  ioFile;      /**      * @var InstallerFile      */     protected $  fileInstaller;      /**      * @var Bluefoot content block repository manager      */     protected $  contentBlockRepository;      /**      * InstallData constructor.      *      * @param Reader $  moduleReader      * @param IoFile $  ioFile      * @param InstallerFile $  fileInstaller      */     public function __construct(         Reader $  moduleReader,         IoFile $  ioFile,         InstallerFile $  fileInstaller,         ContentBlockRepository $  contentBlockRepository     ) {         $  this->moduleReader = $  moduleReader;         $  this->ioFile = $  ioFile;         $  this->fileInstaller = $  fileInstaller;         $  this->contentBlockRepository = $  contentBlockRepository;     }      /**      * Installs data for a module      *      * @param ModuleDataSetupInterface $  setup      * @param ModuleContextInterface $  context      */     public function install(ModuleDataSetupInterface $  setup, ModuleContextInterface $  context)     {         $  setup->startSetup();          $  buttonItemBlock = $  this->contentBlockRepository->getByIdentifier('button_item');         var_dump($  buttonItemBlock);exit;          //Install the blocks and attributes         //$  this->installData($  setup);          $  setup->endSetup();     } }
