I implemented Google’s Sitelinks Search Box to my site. It was working very well. But today I cheked again on Google Structured Data Testing Tool and something was wrong. Now I’m getting below error:
And my implementation is:
<script type="application/ld+json">
{
  "@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"
  }
}
</script>
When I check the JSON on the JSON-LD playground 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?
