• Magento Dev: Please run bin/magento setup:di:compile then check.
• jhon jhon doe: after run this command still getting this issue
• Magento Dev: I think you did not use Magento\Framework\App\Action\Context $context in your constructor if not please do and try again.

Answer 1

You have to add parent dependencies in your public function __construct()

public function __construct(
 \Magento\Framework\Model\Context $context,
 \Magento\Framework\Registry $registry,
 \Magento\Authorization\Model\ResourceModel\Role $resource,
 \Magento\Authorization\Model\ResourceModel\Role\Collection $resourceCollection,
 \Sugarcode\Test\Model\Total\FeeFactory $feeFactory,
 array $data = []
) {
 parent::__construct($context, $registry, $resource, $resourceCollection, $data);
 $this->_feeFactory = $feeFactory;
}

Then remove your generated folder, clean cache and check again.

• jhon jhon doe: facing this error Fatal error: Uncaught TypeError: Argument 2 passed to Magento\Framework\Model\AbstractModel::__construct() must be an instance of Magento\Framework\Registry, none given, called in /home/dukaania/public_html/testing2/app/code/Sugarcode/Test/Model/Total/Fee.php on line 37 and defined in
• Dinesh Yadav: Remove your generated and cache folders and check again.
• Dinesh Yadav: Check my updated answer
• Dinesh Yadav: Check and let me know if you still face any error.
• jhon jhon doe: now i am not able to login my admin panel

Answer 2

You just need to replace your constructor and need to clear generation. Below I have added constructor code please update it in your file and check after that.

public function __construct(
 \Magento\Framework\Model\Context $context,
 \Magento\Framework\Registry $registry,
 \Magento\Framework\Model\ResourceModel\AbstractResource $resource = null,
 \Magento\Framework\Data\Collection\AbstractDb $resourceCollection = null,
 array $data = array()
 ) {
 parent::__construct($context, $registry, $resource, $resourceCollection, $data);
 }

Still you have any query let me know.
