Solution

I got solution of my own problem, actually there was a problem in product data, product data coming was invalid due to that it was not rendering phtml file of listing page. So I just added try catch block in foreach at Magento_Catalog/templates/product/list.phtml and it's now working fine. Here is the code after changes I have made

<?php foreach ($_productCollection as $_product): ?>
            <?php try { ?>
            <?php /* @escapeNotVerified */ echo($iterator++ == 1) ? '<li class="item product product-item">' : '</li><li class="item product product-item">' ?>
            <div class="product-item-info" data-container="product-grid">
                <?php
                $productImage = $block->getImage($_product, $image);
                if ($pos != null) {
                    $position = ' style="left:' . $productImage->getWidth() . 'px;'
                        . 'top:' . $productImage->getHeight() . 'px;"';
                }
                ?>
                <!--DO NOT MODIFY. TRACKER DIV WRAPPER START-->
                <div data-is-trackable="true" data-tracking-context="<?php echo $tracker_constants::PRODUCT_CLICK; ?>" data-event-properties=
                '{"product_id": <?php echo $_product->getId() ?>,
                    "sku": "<?php echo $_product->getSku() ?>",
                    "product_price": <?php echo $_product->getFinalPrice() ?>,
                    "source": "Catalog Page"
                     }'>
                    <!--DO NOT MODIFY. TRACKER DIV WRAPPER TILL HERE-->
                    <?php // Product Image ?>
                    <a href="<?php /* @escapeNotVerified */ echo $_product->getProductUrl() ?>" class="product photo product-item-photo" tabindex="-1">
                        <?php echo $productImage->toHtml(); ?>
                    </a>
                </div>
        ...
        ...
        ...
        ...
         <?php }
            catch (\Exception $err) {
                //echo $err->getMessage();
            }
        ?>
        <?php endforeach; ?>
