Error while running bin/magento setup:di:compile

Question

After running bin/magento setup:di:compile I get the following error.

Errors during compilation:

Vendor\Module\Ui\Component\DataProvider\OutfitProvider Incompatible argument type: Required type: string. Actual type: \Allure\Celebrities\Ui\Component\DataProvider\name; File: /var/www/vhosts/phoenix/app/code/Vendor/Module/Ui/Component/DataProvider/OutfitProvider.php

Here is the code on Ui listing

<dataSource name="outfit_listing_data_source">
 <argument name="dataProvider" xsi:type="configurableObject">
 <argument name="class" xsi:type="string">Vendor\Module\Ui\Component\DataProvider\OutfitProvider</argument>
 <argument name="name" xsi:type="string">outfit_listing_data_source</argument>
 <argument name="primaryFieldName" xsi:type="string">celebrity_outfit_id</argument>
 <argument name="requestFieldName" xsi:type="string">id</argument>
 <argument name="data" xsi:type="array">
 <item name="config" xsi:type="array">
 <item name="update_url" xsi:type="url" path="mui/index/render"/>
 </item>
 </argument>
 </argument>
 <argument name="data" xsi:type="array">
 <item name="js_config" xsi:type="array">

Class

 use Magento\Ui\DataProvider\AbstractDataProvider;
 use Magento\Framework\App\Request\Http;
 use Vendor\Module\Model\ResourceModel\Outfit\CollectionFactory as OutfitCollectionFactory;
 use Magento\Framework\Session\SessionManagerInterface;
 use Magento\Framework\View\Element\UiComponent\DataProvider\DataProviderInterface;
 class OutfitProvider extends AbstractDataProvider implements DataProviderInterface
 {
 protected $_outfitCollection;
 protected $_request;
 protected $_sessionManger;
 public function __construct(
 $name,
 $primaryFieldName,
 $requestFieldName,
 array $meta = [],
 array $data = [],
 OutfitCollectionFactory $outfitCollection,
 Http $request,
 SessionManagerInterface $sessionManager
 ) {
 parent::__construct($name, $primaryFieldName, $requestFieldName, $meta, $data);
 $this->_request = $request;
 $this->_sessionManger = $sessionManager;
 $this->_outfitCollection = $outfitCollection;
 $this->initCollection();
 }
 public function initCollection()
 {
 $id = $this->_request->getParam("id");
 if(isset($id))
 {
 $this->_sessionManger->setCelebrityId($id);
 }
 $collection = $this->_outfitCollection->create();
 $this->collection = $collection;
 $this->collection->addFieldToFilter("celebrity_id", array("eq" => $this->_sessionManger->getCelebrityId()));
 }
 }

• fmsthird: can you change the order of your construct like this: $name, $primaryFieldName, $requestFieldName, OutfitCollectionFactory $outfitCollection, Http $request, SessionManagerInterface $sessionManager, array $meta = [], array $data = []
• Avesh Naik: Problem didn't get solved

Answer 1

add the docblock to the __construct method and type hint as string the following $name, $primaryFieldName, $requestFieldName.

/**
 * @param string $name
 * @param string $primaryFieldName
 * @param string $requestFieldName
 * @param array $meta
 * @param array $data
 * @param OutfitCollectionFactory $outfitCollection
 * @param Http $request
 * @param SessionManagerInterface $sessionManager
 */

Also, your constructor parameters with default values should be added last.

• Avesh Naik: Didn't worked Is anything i am missing?
• Marius: Strange. That was usually the problem for me.
• Avesh Naik: Previously it was showing error two times. Now only once. I am developing on 2.3
• Avesh Naik: Did i done right thing in ui listing file ?
• Marius: aha...maybe there is one other data provider or other class with the same issue.
