Mapper_parsing_exception while indexing json document

Hi,
actions=[{'id':0 ,'imgurl':'abc', 'description':'abc'} , {} ,{}...]
I have such json arrays,
when i run
bulk(es,actions,index="index_name",doc_type="json") in python
i get the following error,
object mapping for [imgurl] tried to parse field [imgurl] as object but found a concrete value.

Check your mapping. The field is defined as an object and not as a text.
May be you indexed other documents previously which don't have the same data structure.
