title: Sitelinks Search Box JSON-LD giving error on Google Structured Data Testing Tool
body: <p>I implemented Google’s <a href="https://developers.google.com/structured-data/slsb-overview" rel="nofollow noreferrer">Sitelinks Search Box</a> to my site. It was working very well. But today I cheked again on <a href="https://developers.google.com/structured-data/testing-tool/" rel="nofollow noreferrer">Google Structured Data Testing Tool</a> and something was wrong. Now I’m getting below error:</p>
  
  <blockquote>
    <p><img src="https://i.stack.imgur.com/EK6Jn.png" alt="Google Structured Data Testing Tool: 2 Errors for WebSite"></p>
  </blockquote>
  
  <p>And my implementation is:</p>
  
  <pre class="lang-html prettyprint-override"><code>&lt;script type="application/ld+json"&gt;
  {
    "@context": "http://schema.org",
    "@type": "WebSite",
    "url": "https://www.saatler.com/",
    "potentialAction": {
      "@type": "SearchAction",
      "target": "https://www.saatler.com/arama?ara={search_term_string}",
      "query-input":"required name=search_term_string"
    }
  }
  &lt;/script&gt;
  </code></pre>
  
  <p>When I check the JSON on <a href="http://json-ld.org/playground/index.html" rel="nofollow noreferrer">the JSON-LD playground</a> everything is looking good. I didn’t change anything on my site. Is Google wrong about this issue? Or the Schema.org structure has changed? What should I do to fix these 2 problems?</p>
