image esc_attr alt in repeater

Hi,

is it possible, that to get the alt-attribute from an image is not possible in a repeater?

In this example the alt-text is shown when outside the repeater, but not inside (same image chosen)

<div class="hero-slider">
        <img src="<?php echo esc_url( $attributes['image-test']['url'] ); ?>" alt="<?php echo esc_attr( $attributes['image-test']['alt'] ); ?>">
        <?php foreach( $attributes['slides'] as $inner ): ?>
            <div class="slide">
                <img src="<?php echo esc_url( $inner['image']['url'] ); ?>" alt="<?php echo esc_attr( $inner['image']['alt'] ); ?>">
            </div>            
        <?php endforeach; ?>
    </div>

Regards
