Type Error occurred when creating object:

I am having the massaction "delete" in the ui_component and it is then process by a controller MassDelete in my adminhtml folder.

like this:

<?php

namespace Apriljune\Testimonial\Controller\Adminhtml\Testimonial;

use Exception;
use Magento\Backend\App\Action;
use Magento\Framework\Controller\ResultFactory;
use Magento\Backend\App\Action\Context;
use Apriljune\Testimonial\Model\ResourceModel\Testimonial\Collection as Testimonial;

/**
* Class MassDelete
*
* @package Apriljune\Testimonial\Controller\Adminhtml\Testimonial
*/
class MassDelete extends Action
{

   /**
    * @var Testimonial
    */
   protected $testimonial;


   /**
    * @param Context $context
    * @param Testimonial $testimonial
    */
   public function __construct( Context $context, Testimonial $testimonial )
   {
       parent::__construct($context);
       $this->testimonial = $testimonial;
   }

   /**
    * Execute action
    *
    * @return \Magento\Backend\Model\View\Result\Redirect
    */
   public function execute()
   {
       $selectedIds = $this->getRequest()->getParams()['selected'];
       if (!is_array($selectedIds)) {
           $this->messageManager->addErrorMessage(__('Please select one or more testimonial.'));
       } else {
           try {
               $collectionSize = count($selectedIds);
               foreach ($selectedIds as $_id) {
                   $testimonial = $this->testimonial->getItems()[$_id];
                   $testimonial->delete();
               }
               $this->messageManager->addSuccessMessage(__('A total of %1 record(s) have been deleted.', $collectionSize));
           } catch (Exception $e) {
               $this->messageManager->addErrorMessage($e->getMessage());
           }
       }

       /** @var \Magento\Backend\Model\View\Result\Redirect $resultRedirect */
       $resultRedirect = $this->resultFactory->create(ResultFactory::TYPE_REDIRECT);
       return $resultRedirect->setPath('*/*/');
   }
}

and massaction is like this in ui-component

<massaction name="listing_massaction">
        <argument name="data" xsi:type="array">
            <item name="config" xsi:type="array">
                <item name="component" xsi:type="string">Magento_Ui/js/grid/tree-massactions</item>
            </item>
        </argument>
        <action name="delete">
            <argument name="data" xsi:type="array">
                <item name="config" xsi:type="array">
                    <item name="type" xsi:type="string">delete</item>
                    <item name="label" xsi:type="string" translate="true">Delete</item>
                    <item name="url" xsi:type="url" path="*/*/MassDelete"/>
                    <item name="confirm" xsi:type="array">
                      <item name="title" xsi:type="string" translate="true">Delete</item>
                      <item name="message" xsi:type="string" translate="true">Are you sure you wan't to delete selected items?</item>
                  </item>
              </item>
          </argument>
      </action>
  </massaction>

Now when i select any row and delete it it redirect to the error page and show the exception

Type Error occurred when creating object: Apriljune\Testimonial\Controller\Adminhtml\Testimonial\MassDelete\Interceptor

i have already tried the solutions,

already done with this process as well

rm -rf var/di/* pub/static/* generated/*
rm -rf var/cache/* var/view_preprocessed/* 

bin/magento setup:upgrade
bin/magento setup:di:compile
bin/magento setup:static-content:deploy
bin/magento cache:flush

Interceptor is already create in /generated i have checked it.

But still the error is there any hint why it is showing error? any typo or logical error? BTW i am using 2.3.3 version of Magento

Re: Type Error occurred when creating object:

Hi @Shoaib967 


I have checked, you backend controller code is correct. This issue belongs to compile issue.
Please set permission then retry:

rm -rf generated/*
chmod -R 777 var/ pub/ generated/
php bin/magento setup:di:compile
php bin/magento cache:flush
chmod -R 777 var/ pub/ generated/

It may help!

Re: Type Error occurred when creating object:

Hi @Shoaib967 ,

 

I have created massDelete controller in one of the module and the content of the controller is like below and it is working fine for me.

public function __construct(
        \Magento\Backend\App\Action\Context $context,
        \Magento\Ui\Component\MassAction\Filter $filter,
        CollectionFactory $collectionFactory
    ) {
        $this->filter = $filter;
        $this->collectionFactory = $collectionFactory;
        parent::__construct($context);
    }

    public function execute()
    {
        $collection = $this->filter->getCollection($this->collectionFactory->create());
        $compDeleted = 0;
        foreach ($collection->getItems() as $comp) {
            $comp->delete();
            ++$compDeleted;
        }
        $this->messageManager->addSuccess(
            __('A total of %1 record(s) have been deleted.', $compDeleted)
        );

        $resultFactory = $this->resultFactory->create(ResultFactory::TYPE_REDIRECT);

        return $resultFactory->setPath('vtn_hlparts/components/index');
    }

Try to change your code is like above code.

 

Hope this helps you!

Re: Type Error occurred when creating object:

Hi @Shoaib967,

 

I hope you have cleared the generated folder and run the setup:di:compile command after the controller changes.

 

Thanks!

Re: Type Error occurred when creating object:

Hi @Shoaib967,

Can you perform below changes

1. In  controller constructor add collection class directly and with factory (same way I have added in my code)

2. Can you share your module structure with us (screenhsot)

3. Last can you simply delete everything from execute and simply write echo and exit command to check whether controller is working fine or not.

 

Hope this helps you!
