Problem with Handlebars: When compiling, TypeError occurs because inverse is not recognized as a function

I've hit a roadblock with an error that I just can't seem to solve. My goal is to dynamically compile a template extracted from a div on the page, provide it with content, and then display it in a designated area of my webpage.

Here's the snippet of code I'm currently working with:

var element = $('#project-list-template');
template = Handlebars.compile(element.html());
console.log('template', template);
$('#detail').html(template({object: projects}));

However, when I try to execute the fourth line, I encounter the following error:

TypeError: inverse is not a function

The console log output for the template function displays:

template function ret()

At first glance, this appears correct as it should indeed return a function. The value of element.html() is as follows:

<div class="resources-list project-detail-active">
        <h2 class="text-uppercase">Liste des projets</h2>
        <div id="projects">
            {{#each object "ul"}}
            <li>
              <a onclick="displayProject('#detail', &quot;{{'@id'}}&quot;,  '#project-detail-template')">
                <h2>
                  {{project_title}}
                </h2>
                <p>
                  {{project_description}}
                </p>
              </a>
            </li>
            {{/each}}
        </div>
      </div>

If you have any insights or suggestions, please feel free to share them. Your help would be greatly appreciated.

Answer №1

The solution to my problem was quite simple. I mistakenly added an unnecessary argument to the each helper.

{{#each items "ul"}}

This caused it to fail, while it should have been just:

{{#each items}}

Initially, I had created a custom helper where I did require the second argument. This led to a careless error during copy/paste that wasted 2 hours of my time...
