title: Graph API error param data must be an array
body: <p>I am trying to load some data to facebook offline events using graph API explorer but ends up with error:</p>
  <pre><code>{&quot;error&quot;: {
      &quot;message&quot;: &quot;(#100) param data must be an array.&quot;,
      &quot;type&quot;: &quot;OAuthException&quot;,
      &quot;code&quot;: 100,
      &quot;fbtrace_id&quot;: &quot;Arug9LHzE4FKTY67LrqQZiJ&quot;
    }
  }
  </code></pre>
  <p>My data is already in array format.</p>
