Hello,

I want to add multiple categories ids but its not working (With 1 category its working) in this widget

https://i.stack.imgur.com/dePEX.png

And also I can't view the information anymore in the front end because I have this error: We're sorry, an error has occurred while generating this content.

These are my log files...

exception.log & debug.log

main.CRITICAL: Notice: Undefined offset: 1 in app/design/frontend/Mimosa/mimosa5/Plazathemes_Categorytab/templates/categorytab/grid.phtml on line 160 {"exception":"[object] (Exception(code: 0): Notice: Undefined offset: 1 in app/design/frontend/Mimosa/mimosa5/Plazathemes_Categorytab/templates/categorytab/grid.phtml on line 160 at vendor/magento/framework/App/ErrorHandler.php:61)"} []

And this is the code of the file grid.phtml:

<?php
    $catIds = $_item->getCategoryIds();
    $_objectManager = \Magento\Framework\App\ObjectManager::getInstance();
    $object_manager = $_objectManager->create('Magento\Catalog\Model\Category')->load($catIds[1]);
?>
<a href="<?php echo $object_manager->getUrl(); ?>" class="cate"><?php echo $object_manager->getName(); ?></a>           
                
<?php if ($templateType): ?>
<?php echo $block->getReviewsSummaryHtml($_item, $templateType,true); ?>
<?php endif; ?>             
<strong class="product-item-name">
    <a title="<?php echo $block->escapeHtml($_item->getName()) ?>"
        href="<?php echo $block->getProductUrl($_item) ?>"
        class="product-item-link">

        <?php echo $block->escapeHtml($_item->getName()) ?>
    </a>
</strong>

<div class="item-price">
    <?php
        echo $block->getProductPrice($_item);
    ?>
</div>
