Answer 1

$this->getCurrentBrand() is returning NULL.

You can solve the issue by ensuring the data is set before the layout is prepared.

Answer 2

You can add code on your theme Magento_LayeredNavigation/templates/layer File.

Previous Code

$brandBlock = $block->getLayout()->createBlock('Rokanthemes\Brand\Block\Brand\View');
$_brand = $brandBlock->getCurrentBrand();

Updated Code

if($this->getRequest()->getControllerName() == 'brand' && $this->getRequest()->getRouteName() == 'rokanthemesbrand') {
$brandBlock = $block->getLayout()->createBlock('Rokanthemes\Brand\Block\Brand\View');
$_brand = $brandBlock->getCurrentBrand();
}
