Recursion doesn't work by including a file within itself!

Hi, I have a file in _includes directory that I'm trying to use like a function by having the file include itself recursively! (which I believe can be done due to this article).

The file _include/courses.html contains:

{% assign orgId = include.lessonID %}

Received ID = {{ orgId }}

{% assign node = include.searchDomain | where:"id",orgId %}
{%- if node.size>0 -%}
  {% comment %}
    If the data was found, then reassing the node from the container array to the right node within the array and proceed.
  {% endcomment %}
  {% assign node = node[0] %}

  <p>CourseID: {{node.id}}</p>
  <p>Name: {{ node.name }}</p>
  <p>Link: {{ node.permalink }}</p>
{%- else -%}
  {%- include courses.html post=post searchDomain=node.content lessonID=lessonID -%}
{%- endif -%}

Now, this is being used by the _layout/courses.html file, containing :

{% include courses.html post=page searchDomain=site.data.courses lessonID=page.lessonInfo.lessonID %}

he file that uses this layout is lister.md:

---
layout: courses
title:  'Test'
lessonInfo:
  lessonID : 1.1
  modName: 'Installing RHEL Server'
  chapterName: 'Using Essential Tools'
---

# There should be some course list around here!

Whenever I try to build the site using bundle exec jekyll serve I get the error:

Liquid Exception: Liquid error (/vm/themeManagement/_includes/courses.html line 16): Nesting too deep included in /_layouts/courses.html
jekyll 3.6.2 | Error: Liquid error (/vm/themeManagement/_includes/courses.html line 16): Nesting too deep included

So, what am I doing wrong and how can I fix it?

The site's _data directory has a file called courses.yaml containing:

- id: 1
  name: 'RHCSA'
  permalink: '/rhcsa'
  description: '<*description>'
  content:
    - id: 1.1
      name: 'Installing RHEL Server'
      permalink: '/rhcsa/installing-rhel-server'
      description: '<*description>'
      content:
        - id: 1.1.1
          name: 'Using Essential Tools'
          permalink: '/rhcsa/installing-rhel-server/using-essential-tools'
          description: '<*description>'
          content:
            - id: 1.1.1.1
              name: 'Man Command'
              permalink: '/rhcsa/installing-rhel-server/using-essential-tools/man-command'
              description: '<*description>'
              content:
            - id: 1.1.1.2
              name: 'Understanding Globbing and Wildcards'
              permalink: '/rhcsa/installing-rhel-server/using-essential-tools/understanding-globbing-and-wildcards'
              description: '<*description>'
              content:

          (...and so on...)

NOTE Through extensive testing I've confirmed that the error is generated solely due to using searchDomain=node.content in _include/courses.html.

Start with the recursive include at line 16 of _include/courses.html and reproduce the failure using bundle exec jekyll serve. Trace how the include receives searchDomain=node.content and reaches Liquid's nesting limit. Done should identify whether this recursion is supported and document or test the resulting behavior.
