Handlebars returning no value but it exists in {{this}}

Using Handlebars 4.0.6 and NodeJS 7.4.0, I output the data that my template is receiving using {{this}}, which outputs:

{ _id: 58a7de1c7275f8208438ae4a,
  author: 589a12b5a08e0c2f24ece4e8,
  dateCreated: 2017-02-18T05:39:40.650Z,
  section: 58a7d57c9ce34527bce7e041,
  slug: 'this-one-will-work',
  title: 'this one will work',
  color: '#d313ff',
  __v: 0,
  fields: 
  [ { fieldId: 58a3cff51da0ea5d00972804,
      fieldSlug: 'color',
      value: '#d313ff',
      _id: 58a7de1c7275f8208438ae4b } ] }

However, using {{color}} or {{this.color}} in the template right below the {{this}} doesn't output anything.

I'm getting the data with mongoose in a Promise, then compiling it, the using res.send().

Here's my compiling function:

    const Handlebars = require('handlebars');
    const fs = require('fs');
    const path = require('path');

    module.exports = (template, data) =>
      new Promise((resolve, reject) => {
        const templateWithFormat = template.endsWith('.hbs') ? template : `${template}.hbs`;
        const templatePath = path.resolve(__dirname, '..', '..', 'templates', templateWithFormat);

        fs.readFile(templatePath, 'utf-8', (err, file) => {
          if (err) reject(err);

          const compiled = Handlebars.compile(file);
          const html = compiled(data);

          resolve(html);
        });
      });

Anyone have any ideas?

Thanks!

You might have a problem if you pass a mongoose model object to Handlebars. (because mongoose wraps an object and adds getters/setters for the properties)

To solve this issue please try running your query with {lean: true} or call modelObj.toObject() before sending it to handlebars.
