I am working on my custom module where I added a button on Configurable products. The Content I was showing through button was by getting the Parent Category ID.

The main issue I am facing is that when I open a product by going through the path(mean Men>Tops>Jackets) it works. But When I directly open the product from HOME PAGE it gives me the error.

In my Block file, I am using these functions

public function getCurrentCategory()
 

 return $this->_registry->registry('current_category');
 

 public function getCurrentProduct()
 

 return $this->_registry->registry('current_product');
 

 public function getCollection($id)
 return $this->_Collection->create()
 ->addFieldToSelect('content')
 ->addFieldToFilter('parent_category',$id)
 ->getData();
 

 public function getDisplay($id)
 return $this->_Collection->create()
 ->addFieldToSelect('display')
 ->addFieldToFilter('parent_category',$id)
 ->getData();
 

For my phtml file, I am using

$cat = $block->getCurrentProduct()->getCategory(); 

 if($block->getCurrentProduct())

 {
 foreach ($cat->getParentCategories() as $parent) 
 if($cat)
 
 $parentId[]= $parent->getId();
 

 $sizeColl = $block->getDisplay($parentId[0]);
 if($sizeColl){
 $block->getCurrentCategory()->getId();
 $display = $sizeColl[0]['display'];

 if($display == 'page'): 
 $Charts=$block->getCollection($parentId[0]); 
 foreach ($Charts as $chart) 
 echo $chart['content'];
 

 else: ?>

Can Anyone help me out with this or suggest me with a better option. Because I need to target Main Parent Category to do my work. Thanks in advance
