type: less produces "Cannot call method 'replace' of undefined"

Gruntfile config:

includeSource: {
  options: {
    basePath: 'app',
    baseUrl: 'public/',
    templates: {
      less: {
        less: '@import "{filePath}";',
        css: '@import "{filePath}";'
      }
    }
  },
  app: {
    files: {
      '.tmp/index.html': 'app/index.tpl.html'
    }
  }
}

Index.html:

<!-- include: "type": "less", "files": "styles/**/*.less" -->

"grunt includeSource" produces: TypeError: Cannot call method 'replace' of undefined node_modules\grunt-include-source\tasks\include_source.js:184:64

What happens when you remove the templates options from your Gruntfile? Since the default template is the same anyway, you don't need it and there might be a bug with merging the templates from the options with the defaults.

Unit tests have been added. I tried adding your templates config to the task and everything seemed to work fine. I'm closing this issue for now since I can't reproduce it and it's over 2 months old now. If you have any other problems, please reopen this issue.
