Blog post category

[Artful-dodger]

Since updating to Blog Post v2.2.0, I’ve encountered the following error during template rendering:

"An exception has been thrown during the rendering of a template (“Missing required parameter for [Route: ] [URI: {slug?}] [Missing parameter: {href}].”) in /var/www/html/drift-in/themes/drift-in-laundry-2/partials/pages-blog-category/mainpage.htm at line 64."

This appears to be related to a redirect or route call from: https://drift-in.co.uk/pages-blog-category/

The error suggests a missing parameter—possibly due to a misconfigured route or incorrect usage of {href} instead of {slug}. I’ve reviewed the template and suspect the issue may stem from a line like:

<a href="{{ 'blog-post' | page({ href: post.slug }) }}">

If the route expects slug, this should likely be:

<a href="{{ 'blog-post' | page({ slug: post.slug }) }}">

Could you please advise on the correct parameter usage for this route under Blog v2.2.0? Also, if there were any changes to route definitions or parameter expectations in the update, a reference to the changelog or migration notes would be appreciated.

Thanks in advance for your help!

@Artful-dodger Hmm, that's odd. There shouldn't be any changes that would have caused this. Can you share the full code for the page where you are having this issue?

[Artful-dodger]

this is the code for the partial that I am using

<div class="lt-row row">
  <!-- Blog page -->
  <div id="col" class="lt-col col l12 m11 s12">
    <div class="masonry post h-entry" id="post-list"  itemscope itemtype='http://schema.org/Blog'>
      {% for post in posts %}
      {# NOTE THIS SECTION #}
      <div class="main idle" itemprop="blogPost">
        <div class="card">
          {% if post.featured_images.count %}
          <div class="card-panel hoverable blue-grey lighten-4">
            {% for image in post.featured_images|slice(0, 1) %}
            <a href="{{ post.url }}" itemprop="url">
              <div class="card-image" id="post-list-featured-images-top-{{ post.id }}">
                <img src="{{ image.path }}"  data-src="{{ image.path }}" alt="{{ image.description != null ? image.description : image.filename }}" title="{{ image.title != null ? image.title : post.title }}" itemprop="image" />

I’ve noticed that the /drift-in-blog/ page on the site automatically redirects to /drift-in-blog/1, which appears to be the first paginated view of the blog which in the older version it didn't it was /drift-in-blog/ . However, the /drift-in-blog/category/ endpoint does not redirect in the same way and currently resolves without any content or guidance.

Would it be possible to review the routing logic for consistency? It might be helpful to either apply a similar redirect to /category/ or introduce a landing view that lists available categories.

Let me know your thoughts.
