 I have code:

 {{{
 data = serializers.serialize("xml", queryset, fields=fields)
 }}}

 if I choose specific fields, which are not JSONField, it is ok. But if I
 choose field, which is JSONField, I receive error
 {{{
  File "/Users/ustnv/PycharmProjects/fpg_nko/venv/lib/python3.6/site-
 packages/django/core/serializers/__init__.py", line 128, in serialize
