title: "(#100) param data must be an array" Facebook Offline Conversions API error
body: <p>I am getting this error on hitting the <code>/events</code> endpoint (POST REQUEST) to upload event. The URL I am hitting is <code>https://graph.facebook.com/v3.2/&lt;EVENT_ID&gt;/events</code> with payload something like this: </p>
  
  <p><code>{'upload_tag': &lt;TIMESTAMP&gt;, 'data': [{'currency': 'USD', 'event_time': &lt;TIMESTAMP&gt;, 'value': 0.0, 'match_key': {'email': '&lt;EMAIL_HASH&gt;'}, 'custom_data': {'event_source': 'event'}}], 'access_token': '&lt;ACCESS_TOKEN&gt;'}</code></p>
  
  <p>But am getting the error that params must be an array which it already is. Any help would be appreciated.</p>
