Item.Image not displaying in Jekyll - jekyll

Question

I have a bunch of portfolio posts in /_works/ and the front matter looks something like this:
title: "Rock in Rio Lisbon 2018"
date: July, 2018
image: "/assets/images/work/rock-in-rio-lisbon-2018.jpg"
categories:
- Intro
slides:
- title: "Rock in Rio Lisbon 2018 Headliner Show for Bruno Mars, Katy Perry, Muse & The Killers"
id: "O-rZ6IFnv9g"
override: true
On the homepage I'm using the Slides.ID to automatically grab the YouTube video's thumbnail. If the front matter includes Override: true it should display what I have defined as the image instead. Here is the what I have:
{% assign works = site.works | reverse %}
{% for item in works limit:9 %}
<li class="{% cycle 'wide','','','','','','','','' %}">
<a href='{{ site.url }}{{ item.url }}'>
{% if item.override %}
{% for item in item.slides limit:1 %}
<img alt="A frame from a video of {{ item.title }}" loading="lazy" src="{{ site.url }}{{ item.image }}" />
{% endfor %}
{% else %}
{% for item in item.slides limit:1 %}
<img alt="A frame from a video of {{ item.title }}" loading="lazy" src="https://img.youtube.com/vi/{{ item.id }}/sddefault.jpg" />
{% endfor %}
{% endif %}
<div class='overlay'>
<div class='thumb-info'>
<h3>{{ item.title }}</h3>
<p>{{ item.categories | sort | join:" • " | escape }}</p>
<p>{{ item.image }}</p>
</div>
</div>
</a>
</li>
{% endfor %}
When Jekyll compiles, the {{ item.image }} is not working…however, if I swap it with {{ item.title }} it does work. Any ideas why this is happening?

Answer 1

You are reusing the 'item' variable in slides, which overwrites it. Rename the variable 'item' to 'slide' when you are looping through the slides, like this:
{% assign works = site.works | reverse %}
{% for item in works limit:9 %}
<li class="{% cycle 'wide','','','','','','','','' %}">
<a href='{{ site.url }}{{ item.url }}'>
{% if item.override %}
{% for slide in item.slides limit:1 %}
<img alt="A frame from a video of {{ slide.title }}" loading="lazy" src="{{ site.url }}{{ slide.image }}" />
{% endfor %}
{% else %}
{% for slide in item.slides limit:1 %}
<img alt="A frame from a video of {{ slide.title }}" loading="lazy" src="https://img.youtube.com/vi/{{ slide.id }}/sddefault.jpg" />
{% endfor %}
{% endif %}
<div class='overlay'>
<div class='thumb-info'>
<h3>{{ item.title }}</h3>
<p>{{ item.categories | sort | join:" • " | escape }}</p>
<p>{{ item.image }}</p>
</div>
</div>
</a>
</li>
{% endfor %}
