I have a custom phtml inside I called attribute.phtml but it's not working:

echo $block->getTemplateFile('Magento_Catalog::product/view/attribute.phtml');

echo $this->getLayout()

        ->createBlock("MagentoFrameworkViewElementTemplate")

        ->setTemplate("Magento_Catalog::product/view/attribute.phtml")

        ->toHtml();

Both showing error only.

Pass Block file as, MagentoCatalogBlockProductViewDescription
Just keep below line in your phtml file,

<?php echo $this->getLayout()->createBlock("MagentoCatalogBlockProductViewDescription")->setTemplate("Magento_Catalog::product/view/attribute.phtml")->toHtml();?>

If you want use the Magento_Catalog::product/view/attribute.phtml you should add important data to the block before layout render it (from the template):

$_product = $block->getProduct();

$_call = $block->getAtCall();

$_code = $block->getAtCode();

$_className = $block->getCssClass();

$_attributeLabel = $block->getAtLabel();

$_attributeType = $block->getAtType();

$_attributeAddAttribute = $block->getAddAttribute();

So according to your needs you can pass block arguments to the createBlock method using third argument:

/**

 * Block Factory

 *

 * @param  string $type

 * @param  string $name

 * @param  array $arguments

 * @return ElementBlockInterface

 */

public function createBlock($type, $name = '', array $arguments = );

Your code should looks like this (I use the SKU-attribute as an example):

$block->getLayout()

        ->createBlock(

            'MagentoFrameworkViewElementTemplate', 

            '', 

            [

                "at_call" => 'getSku',

                "at_code" => 'sku',

                "css_class" => 'sku',

                "at_label" => 'default',

                "add_attribute" => 'itemprop="sku"',

                "product" => $block->getProduct() // Here should be real current product, you should load it in your main block!

            ])

        ->setTemplate("Magento_Catalog::product/view/attribute.phtml")

        ->toHtml();

PS: Try to change $this to the $block in your code:

<?php echo ($block->getTemplateFile('Magento_Catalog::product/view/attribute.phtml')) ;?>

<?php echo $block->getLayout()->createBlock("MagentoFrameworkViewElementTemplate")->setTemplate("Magento_Catalog::product/view/attribute.phtml")->toHtml();?>

In Magento 2 you should use the $block variable inside a template, not $this. Here you can find additional info.
