 $model = 'Magento\Framework\View\Element\UiComponent\DataProvider\Document',
 $connection = null,
 \Magento\Framework\Model\ResourceModel\Db\AbstractDb $resource = null 
)
{
 parent::__construct($entityFactory, $logger, $fetchStrategy, $eventManager, $connection, $resource);
 $this->_eventPrefix = $eventPrefix;
 $this->_eventObject = $eventObject;
 $this->_init($model, $resourceModel);
 $this->setMainTable($mainTable);
}

Answer 1

Please $connection use as below in the Collection.php
 public function __construct(
 ...
 \Magento\Framework\DB\Adapter\AdapterInterface $connection = null,
 ...
) {
 ...
}

Again do the compile

• cashtrader: Hello, i tried that but now the compile is not running. Neither the upgrade or any other commands.
• Nagaraju Kasa: what exact magento version you are using ? 2.21 (or) 2.1.x ?
• Nagaraju Kasa: you are welcome

Answer 2

I have changed the line

 $connection = null,

with

\Magento\Framework\DB\Adapter\AdapterInterface $connection = null,

Now is working!

• Nagaraju Kasa: yes that what i told good
• seanbreeden: This is exactly what @NagarajuKasa recommended. Why didn't you just accept his answer?
