title: How to Create Elasticsearch Point in Time (PIT)?
body: <p>I'm trying to use the search_after parameter with a point in time (PIT) to paginate search results. <a href="https://www.elastic.co/guide/en/elasticsearch/reference/7.x/paginate-search-results.html#search-after" rel="noreferrer">This</a> is the documentation section I'm consulting.</p>
  <p>I'm making a POST to <code>/my-index/_pit?keep_alive=1m</code>.<br />
  The <code>/_pit</code> endpoint only accepts the POST method (if I try GET, it says only POST is accepted), and per the doc, does not take a request body. However, the response I receive is a 400 with this message:</p>
  <blockquote>
  <p>&quot;type&quot;: &quot;parse_exception&quot;,<br />
  &quot;reason&quot;: &quot;request body is required&quot;</p>
  </blockquote>
  <p>I can't find any other examples of a <code>/_pit</code> request and I'm just confused by these responses.<br />
  Has anyone successfully gotten back a PIT?</p>
  <p>In case it's relevant, we have a managed elastic cloud deployment on a standard subscription.</p>
