Answer 1

You can create a template file in your theme this core file :

vendor/magento/module-sales/view/frontend/templates/email/shipment/track.phtml

and add condition before this function

getTracksCollection

you can add condition like this

<?php if ($_shipment && $_order): ?>

So that issue will fixed for magento 2.3.1

Answer 2

We had the same issue in Magento 2.2.8. The reason is, when you try to review mail template there is not available order object.

I have fixed it in this way.

Created a template file in the custom theme: Magento_Sales/templates/email/shipment/track.phtml

<?php
/**
 * Copyright © Magento, Inc. All rights reserved.
 * See COPYING.txt for license details.
 */

// @codingStandardsIgnoreFile

?>
<?php $_shipment = $block->getShipment() ?>
<?php $_order = $block->getOrder() ?>
<?php if ($_shipment && $_order): ?>
    <?php $trackCollection = $_order->getTracksCollection($_shipment->getId()) ?>
    <br />
    <table class="shipment-track">
        <thead>
        <tr>
            <th><?= /* @escapeNotVerified */  __('Shipped By') ?></th>
            <th><?= /* @escapeNotVerified */  __('Tracking Number') ?></th>
        </tr>
        </thead>
        <tbody>
        <?php if ($trackCollection): ?>
            <?php foreach ($trackCollection as $_item): ?>
                <tr>
                    <td><?= $block->escapeHtml($_item->getTitle()) ?>:</td>
                    <td><?= $block->escapeHtml($_item->getNumber()) ?></td>
                </tr>
            <?php endforeach ?>
        <?php endif; ?>
        </tbody>
    </table>
<?php endif; ?>
