How to solve above complication errors?

This is because your parent constructor has redundant arguments or not correct . In your case, need to remove arguments: $storeManager and $metadataPool.

app\code\Custom\Module\Model\ResourceModel\Posts\Grid\Collection.php

parent::__construct(
        $entityFactory,
        $logger,
        $fetchStrategy,
        $eventManager,
        //$storeManager, <= Remove it
        //$metadataPool, <= Remove it
        $connection,
        $resource
    );
  • From app\code\Custom\Module\Model\ResourceModel\Posts\Grid\Collection.php need to remove right? – Ankit Shah Oct 20 '16 at 5:55
  • Yes, it is @AnkitShah – Khoa TruongDinh Oct 20 '16 at 5:58
