Looks like your curl call returns null sometimes. You can change this line return $allData; in the getCustomerReview method with this

return $allData ?? ['reviews' => []];

  • After update : return $allData ?? ['reviews' => []];, i am getting Error filtering template: Notice: Undefined index: reviews in C:\xampp\htdocs\m3\app\code\Zero\Storelocator\view\frontend\templates\google_reviews.phtml on line 4

You need to wrap the code with the isset condition before getting the data. You can use the below code for phtml file:

<?php
$allcollection = $this->getCustomerReview();
if($allcollection && isset($allcollection['reviews'])) {
    $allData = array_slice($allcollection['reviews'], 0, 5, true);
    foreach ($allData as $data) {  
        if (array_key_exists('comment', $data)) {
?> 
            <!-- Star Rating  -->
            <div><?php echo $data['starRating'] ?></div> 

            <!-- Comment  -->
            <div><?php echo $data['comment'] ?></div>

            <!-- Reviewer Name  -->
            <div><?php echo $data['reviewer']['displayName']; ?></div>

            <!-- review Age   -->
            <div><?php echo $data['createTime']; ?></div><br>
        
<?php   } 
    } 
}   
?>
