got an unexpected keyword argument 'data_only'

I use elasticsearch-dsl == 6.2.1

{
  "name" : "67G84Xb",
  "cluster_name" : "elasticsearch",
  "cluster_uuid" : "C4Q4oVYHTIyTWtpUyUP_lA",
  "version" : {
    "number" : "6.2.4",
    "build_hash" : "ccec39f",
    "build_date" : "2018-04-12T20:37:28.497551Z",
    "build_snapshot" : false,
    "lucene_version" : "7.2.1",
    "minimum_wire_compatibility_version" : "5.6.0",
    "minimum_index_compatibility_version" : "5.0.0"
  },
  "tagline" : "You Know, for Search"
}

Got error:

  File "/elasticsearch_dsl/field.py", line 163, in _wrap
    return self._doc_class.from_es(data, data_only=True)
TypeError: from_es() got an unexpected keyword argument 'data_only'

Problem is that PriceCondition cannot extend DocType but must be extending InnerDoc.I will make a note to fix it so that it won’t break but for now just change its base from BaseDocType to InnerDoc and it should help.

I’m having similar issue, with

elasticsearch==6.3.1 elasticsearch-dsl==6.3.1

 class ReviewMeta(InnerDoc):

     id = Integer()
     name = Keyword()
     tags = Keyword()
     location = GeoPoint()
     area_names = Keyword()


 class ReviewMetaSearchClickLogDoc(DocType):

     id = Integer()
     created_at = Date()
     search_log_id = Integer()
     review_meta = Object(ReviewMeta)
     position = Integer()

     class Index:
         name = REVIEWMETA_SEARCH_CLICK_LOG_INDEX


 class ReviewMetaSearchLogDoc(DocType):

     id = Integer()
     created_at = Date()
     user = Object(User)
     result_count = Integer()
     search_data = Object(dynamic=True)
     clicks = Nested(ReviewMetaSearchClickLogDoc, include_in_parent=True)

     class Index:
         name = REVIEWMETA_SEARCH_LOG_INDEX

I guess the problem is Nested(ReviewMetaSearchClickLogDoc, include_in_parent=True) , why is it a problametic, and how can I fix it?
