Why is it giving an error?

Question

WordPress

<div class="header__logo">
                        <a href="#">
                            <?php 
                            $image = get_field('logo');
                            if( !empty($image) ): 
                            ?>
    <img src="<?php echo $image['url']; ?>" alt="StoriesCafe"/>

<?php endif; ?>
                        </a>

I wanted to connect the image like this, but it gives an error

The get_field function internally tries to get the logo key (which doesn't exist) from an array or ArrayAccess descendant. So he writes that illegal offset. And what exactly is wrong there, smoke the documentation
