title: JSONField in Serializers of Django Rest Framework
body: <p>I am trying to create a serializer which has only one JSONField</p>
  
  <pre><code>class DataSerializer(serializers.Serializer):
      data = serializers.JSONField()
  </code></pre>
  
  <p>When I am trying to use this serializer in the shell as - </p>
  
  <pre><code>&gt;&gt;&gt; s = DataSerializer(data={"name": "Tom"})
  &gt;&gt;&gt; s.is_valid()
  False
  &gt;&gt;&gt; s.errors
  {'data': [ErrorDetail(string='This field is required.', code='required')]}
  </code></pre>
  
  <p>I don't know what I am doing wrong. Please bear with me if its a too simple question as I am new to using DRF.</p>
