Magento2 Override Block – Invalid Template File Problem – How to Fix

blockscataloglayoutmagento2overrides

I would like to Override Magento\Catalog\Block\Product\View\Description, but I've got:

[2017-08-21 16:03:47] main.CRITICAL: Invalid template file:
'product/view/attribute.phtml' in module: 'Test_Catalog' block's name:
'product.info.sku' [] []

and detail.phtml is missing on frontend on product page.

I have done:

etc/di.xml 

<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:ObjectManager/etc/config.xsd">
    <preference for="Magento\Catalog\Block\Product\View\Description" type="Test\Catalog\Block\Product\View\Description" />
</config>

in Test/Catalog/Block/Product/View/Description:

<?php
namespace Test\Catalog\Block\Product\View;

class Description extends \Magento\Catalog\Block\Product\View\Description
{

    /**
     * @return array|bool
     */
    public function getConfigProductChild()
    {
         //function returns child products in array
    }
}

I'm using TemplateMonster Theme so I would like to use getConfigProductChild function in :

project/app/design/frontend/TemplateMonster/framework/Magento_Catalog/templates/product/view/details.phtml

I read that I should type referenceBlock with template and Mine block but it doest works (or I did something wrong?).
Tried something like that:

in view/frontend/layout/default.xml of mine module:

 <page xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:View/Layout/etc/page_configuration.xsd">
    <body>
        <referenceBlock name="product.info.details" class="Test\Catalog\Block\Product\View\Description" template="Magento_Catalog::product/view/details.phtml" after="product.info.media"/>
    </body>
</page>

Instead of Magento_Catalog I tried also use TemplateMonser etc.

Do You know what's the problem?

EDIT:

path for missing pthml: 

project/app/design/frontend/TemplateMonster/framework/Magento_Catalog/templates/product/view/details.phtml

layout using details.phtml:
project/app/design/frontend/TemplateMonster/framework/Magento_Catalog/layout/catalog_product_view.xml

<body>
        <referenceContainer name="content">
            <block class="Magento\Catalog\Block\Product\View\Description" name="product.info.details" template="product/view/details.phtml" after="product.info.media">
                <block class="Magento\Catalog\Block\Product\View\Description" name="product.info.description" template="product/view/attribute.phtml" group="detailed_info">
                    <arguments>
                        <argument name="at_call" xsi:type="string">getDescription</argument>
                        <argument name="at_code" xsi:type="string">description</argument>
                        <argument name="css_class" xsi:type="string">description</argument>
                        <argument name="at_label" xsi:type="string">none</argument>
                        <argument name="title" translate="true" xsi:type="string">Details</argument>
                    </arguments>
                </block>
                <block class="Magento\Catalog\Block\Product\View\Attributes" name="product.attributes" as="additional" template="product/view/attributes.phtml" group="detailed_info">
                    <arguments>
                        <argument translate="true" name="title" xsi:type="string">More Information</argument>
                    </arguments>
                </block>
            </block>
        </referenceBlock>
</body>

In your current theme, you need to make change in catalog_product_view.xml file as below.

If your new template still exist in Magento_Catalog module then update code like below:

<block class="Test\Catalog\Block\Product\View\Description" name="product.info.details" template="Magento_Catalog::product/view/details.phtml" after="product.info.media" remove ="true"/>

If your new template still exist in Test_Catalog module then update code like below:

<block class="Test\Catalog\Block\Product\View\Description" name="product.info.details" template="Test_Catalog::product/view/details.phtml" after="product.info.media" remove ="true"/>
