Based on your question, the constructor you are using missing ScopeConfigInterface, because it's using by your parent construct.

Your code:

parent::__construct(
    $entityFactory,
    $logger,
    $fetchStrategy,
    $eventManager,
    $connection,
    $resource
);

It should be

parent::__construct(
    $entityFactory,
    $logger,
    $fetchStrategy,
    $eventManager,
    $scopeConfig,
    $connection,
    $resource
);

You will need to add the scope config into your constructor and make it matches what you see in parent::__construct().
