Error: missing partial: 'html/template'

[Paceaux]

I have been struggling quite a bit with generating a static site using gulp, handlebars, and handlebars layouts. I suspect I am doing something wrong but I cannot for the life of me figure out what it is. I am not sure if I am applying/ identifying a layout file correctly. Should it be as a partial?

I am using the following:

• gulp 4.0.2
• gulp hb 8.0.0
  -handlebars-layouts 3.1.4

This is in my gulp file:

const { src, dest } = require('gulp');
const GulpHb = require('gulp-hb');

const {handlebars: config } = require('../config');

function getHbStream(config) {
  return GulpHb({ debug: true })
    .helpers(require('handlebars-layouts'))
    .partials(config.partials)
    .partials(config.layouts)
    .helpers({...config.helpers})
    .data(config.data);
}

function buildHandlebars() {
  const hbStream = getHbStream(config);

  return src(config.src)
    .pipe(hbStream)
    .pipe(dest(config.dest));
}

module.exports = buildHandlebars;

the configuration information looks like this:

  handlebars: {
    watch: path.join(sourceDir, sourceDirs.templates, '**/*.hbs'),
    src: path.join(sourceDir,sourceDirs.templates,'*.hbs' ),
    layouts: path.join(sourceDir,sourceDirs.templates,'layouts/*.hbs' ),
    dest: buildDir,
    data: path.join(sourceDir, 'data', '*.json'),
    partials: path.join(sourceDir, sourceDirs.templates, 'partials', '**/*.hbs'),
    helpers: {
      'equal': function handlebarsEqualHelper(name, value, options) {
        return this.context[name] === value ? options.fn(this) : options.inverse(this);
      },
      'set': function _handlebarsVariablesHelper(name, options) {
        const content = options.fn(this);
        this.context[name] = content;
      },
    },
  },

What is the correct value for a layout partial?
In none of my handlebars files do I have an 'html/template' partial. I'm assuming this is an internal of handlebars-layouts.
