Question

I am facing an issue on the Live site that category collection only returns the specific level categories the same code is working fine on Localhost

Here is My Code

public function getAllCategory(int $storeId = 0){


    $objectManager = \Magento\Framework\App\ObjectManager::getInstance();
    $storeManager = $objectManager->get('\Magento\Store\Model\StoreManagerInterface');
    $baseUrl = $storeManager->getStore()->getBaseUrl();


    $catagoryList=array();
    $result=array();
    $collection = $this->_categoryCollectionFactory->create();
    $collection->addAttributeToSelect('*');
    $collection->addAttributeToFilter('is_active', 1);
    $collection->setStore($storeId);

    if ($collection->count() < 1) {
        $result[0]['success']=false;
        $message = __('Category doesn\'t exist.');
        $result[0]['message']=$this->appApiHelper->translate($message);
        $result[0]['data']=null;

        return $result;
    }

    $collectionChild = $this->_categoryCollectionFactory->create();
    $collectionChild->addAttributeToSelect('*');
    $collection->addAttributeToFilter('level', 4);
    $collectionChild->addAttributeToFilter('is_active', 1);
    $collectionChild->setStore($storeId);
    $result[0]['success']=true;
    if ($collectionChild->count() < 1) {
        foreach ($collection as $category) {

            $catagoryList=array();
            $catagoryList['entity_id'] = $category['entity_id'];
            $catagoryList['name'] = $category->getName();
            if($category->getImageUrl() != null)
            {
                $catagoryList['image_url'] = $baseUrl.$category->getImageUrl();
            }
            else
            {
                $catagoryList['image_url'] = false;
            }

            $catagoryList['url_path'] = $category->getUrlPath();
            $catagoryList['description'] = $category->getDescription();
            $catagoryList['tag_line'] = $category->getTagLine();
            $result[0]['data'][]=$catagoryList;

        }
    }else{
        foreach ($collection as $category) {
