Why files in fields no output?

Blueprint:

  - width: 1/3
    fields:
      silder:
        label: Slider
        type: files
        layout: cards
        image:
          cover: true
          ratio: 16/9

Template:

<?php
$images = $page->slider()->toFiles();
foreach($images as $image): ?>
    <img src="<?= $image->url() ?>" alt="">
<?php endforeach ?>

However, there is no output at all.

Typo? If the field is accidentally called silder instead of slider

Oh…sorry, thank you texnixe!
