Could not resolve pagination key in template data

[einomi]

Describe the bug I'm trying to generate pages from _data/data1.json file using the pagination feature but get Could not resolve pagination key in template data error during the build. This is the example repo https://github.com/frontenso/500k-pages-with-11ty What do I do wrong?

To Reproduce Steps to reproduce the behavior:

1. Go to https://github.com/frontenso/500k-pages-with-11ty
2. Run npm run start

• Mac
• Eleventy Version 0.12.1

Additional Information pages.njk contents:

---
title: Hello
layout: "base.njk"
pagination:
    data: data1.items
    size: 1
    alias: item
permalink: "{{ item.slug }}/"
---

{% block content %}
  <h1>{{ item.name }}</h1>
{% endblock %}

I think your code and logic is correct, but per https://www.11ty.dev/docs/config/#directory-for-global-data-files, the _data/ directory should be within your src/ directory.

---

# Build site, should fail to resolve `data1.items` object and exit w/ errorcode.
npm run build:eleventy

# Move ./_data/ directory into the ./src/ directory...
mv _data src

## Rebuild site...
npm run build:eleventy

Oh, thanks @pdehaan! It works now.

By the way, I didn't know how to add a custom error handler to 11ty so I ended up with spawning a process with a custom script https://github.com/frontenso/500k-pages-with-11ty/blob/master/scripts/eleventy-dev.js but I will probably create a new issue on this
