Magento 2.3.4 Tabs Initialization Error – Fix Method Call Issue

magento2.3.4product-pagereview

In Magento 2.3.4 product page when click review text or reviews and not going to review form or Customer review

Before it's working fine in Magento 2.2.4

and it's an error coming from the below core file in this function

/vendor/magento/module-review/view/frontend/web/js/process-reviews.js

$(function () {
    $('.product-info-main .reviews-actions a').click(function (event) {
        var anchor, addReviewBlock;

        event.preventDefault();
        anchor = $(this).attr('href').replace(/^.*?(#|$)/, '');
        addReviewBlock = $('#' + anchor);

        if (addReviewBlock.length) {
            $('.product.data.items [data-role="content"]').each(function (index) { //eslint-disable-line
                if (this.id == 'reviews') { //eslint-disable-line eqeqeq
                    $('.product.data.items').tabs('activate', index);
                }
            });
            $('html, body').animate({
                scrollTop: addReviewBlock.offset().top - 50
            }, 300);
        }

    });
});

I checked but I can't find proper solution
Does anyone know about this issue?

Any help would be appreciated.

Thanks.

Try this one. The issue may be resolved by putting the below code into the details.phtml of Magento_Catalog module.

<script type="text/javascript">
    require(['jquery','jquery/ui'], function($) {
    //Change the below class if not matching
        $("div.product.data.items").tabs();
    });
</script>

Vendor Path - <magento-root>/vendor/magento/module-catalog/view/frontend/templates/product/view/details.phtml

For theme - <magento-root>/app/design/frontend/Vendor/ThemeName/Magento_Catalog/templates/ product/view/details.phtml

Note: Copy details.phtml file from vendor path if not present in the respective theme directory.

Clear the cache if prompted.

This is purely workaround and worked for me very well in 2.3.4 instance.

Possible ways to debug further.

1. First try

Check If Flat catalog for category ENABLED then DISABLE it or if Flat Catalog for category found DISABLED then ENABLE it.
Perform full reindexing
Then try to save any category again, it should work.

2. If not solving then try to add the instance check condition like below: Culprit attribute can be found by removing the comment in the first if condition.

    foreach ($category->getDesignAttributes() as $designAttribute) {
     if(!$designAttribute instanceOf \Magento\Eav\Model\Entity\Attribute){
     //$designAttribute->getAttributeCode(); die('s');
     continue;
    }

        if ($this->isCategoryAttributeChanged($designAttribute->getAttributeCode(), $category)) {
            $this->cacheTypeList->invalidate(
                [
                    \Magento\PageCache\Model\Cache\Type::TYPE_IDENTIFIER,
                    \Magento\Framework\App\Cache\Type\Layout::TYPE_IDENTIFIER
                ]
            );
            break;
        }
 }

3rd thing you may try the last Review all the category attributes which are showing after executing the below query.

Compare with native Magento's instance table of the same entity_type_id.

SELECT * FROM `eav_attribute` WHERE `entity_type_id` = 3
