I’m running Ghost 2.18.1. And when I visit a blog post page I’m seeing this error occur (heroku logs):

This error doesn’t occur when I run ghost locally, the blog post appears normally. Only when it is pushed onto heroku. I don’t see any documentation as to what this error means or why it can occur.

Hey @CMCDragonkai :wave: The error indicates that ‘matches’ validator failed for page resource, which is most likely triggered in slug field validation. Could you please provide the request values that produce this error?

Hi @naz, can you elaborate what is a matches validator. And what exactly is a slug field validation.

I don’t know how to provide request values you’re asking for. Are you asking for the exact page at which this is happening? Well here’s the page where this is happening: Service Abstraction and Communication Flows | Matrix AI

If I check heroku logs it is always showing that validation error occurring over and over on each page load.

The handlebar template for the post.hbs is:

{{!< default}}

{{#post}}
  {{> post-meta}}
  {{!--  <div class="post-metadata-container" data-stellar-ratio="0.75">  --}}
  <div class="post-metadata-container">
    <div class="post-metadata-content">
    {{> title}}
    {{!--  {{> sidebar}}  --}}
    </div>
  </div>

  <div class="push-article">
    {{! Temporary indentation shift for Handlebars issue }}
    {{> content}}
  </div>

  <div class="container">
      <div class="author animated fadeIn clearfix">
          {{#primary_author}}
              <img src="{{img_url profile_image}}" alt="{{name}}" />
              <div class="info">
                  <a href="{{url}}" class="name">{{name}}</a>
                  <p class="bio">{{bio}}</p>
              </div>
          {{/primary_author}}
      </div>
  </div>
  {{> comments}}
{{/post}}

This error occurs when the server receives an incorrect page option. For example, if you would do a call similar to this: GET http://ghost.local/ghost/api/v2/content/posts/?key=XXX&page=invalid_page or when you are using {{get}} helper inside of handlebars template similar error can be triggered with syntax like this:

{{#get "tags" limit="5" page="undefined"}}{{tags}}{{/get}}

On the template you provided, there’s no use of page parameter. Could you please check if it’s used in any of the partials and if the value passed is correct?
