[CLOSED] It was my mistake, there are other code that called **save()** prior to **init()**. Changing the order fixes this exception.
* * *
I'm completely new to ES, trying out **ES 6.2.3** with **ES DSL 6.2.1** (official client lib for Python). Referring to documentation, I defined below model by using Document.
```
class Company(Document):
hq_country_iso = Keyword()
co_name = Text()
class Index:
name = 'company'
def save(self, **kwargs):
return super(Company, self).save(**kwargs)
```
When calling **Company.init()** of Document API to create index, ES throws below exception. However, the index is still created and I'm able store data into ES (I haven't try production mode though). If I remove the hq\_country\_iso KEYWORD field or change it as TEXT field, this exception will go away. I'd tried following but have no luck:
- ensured that the index doesn't exist (the word **current\_type** in error msg is beyond my comprehension)
- cleared cache
- restarted ES
Any clue what could be causing this? Thanks.
