title: param is missing or empty - jsonapi rails
body: <p>The request payload is as follows.</p>
  
  <pre><code>{"vertical":{"certification_ids":[7,1]}}
  </code></pre>
  
  <p>permit data is as follows</p>
  
  <pre><code>def create_params
    params.require(:vertical).permit(certification_ids: [])
  end
  </code></pre>
  
  <p>But i am getting the following response</p>
  
  <pre><code>{"errors":"param is missing or the value is empty: vertical"}
  </code></pre>
  
  <p>params that is seen in the rails console is as follows</p>
  
  <pre><code>"params":{"_jsonapi":{"vertical":{"certification_ids":[7]}},"vertical_id":"1"},
  </code></pre>
  
  <p>So i assume the issue is due to the "_jsonapi" key that is somehow shown in the params.</p>
  
  <p>Any idea on how to fix this issue?</p>
  
  <p>Note: I was using jsonapi gem in my project. But i dont want to use it anymore on new apis.</p>
