我试图构建一个json字符串并将其作为文档写入es但是我得到了一个映射错误。我使用了类型json并遵循api指南，使用下面链接的elasticsearch python模块。
https://elasticsearch-py.readthedocs.org/en/master/api.html
这是我创建索引和编写文档的代码。我不包括id，因为es中的id字段应该自动递增：
def create_es_index(es, index):
es.indices.create(index=index, ignore=400)
def write_to_es(es, index, doc, doc_type):
res = es.index(index=index, doc_type=doc_type, body=doc)
es.indices.refresh(index=index)
return res['created']
json string
