Recently i have upgraded from 6.7 to 7.8 in a single node server.Now i am facing below error while trying to clear/reindex from the application server.
```auto
**[error]** **Message: {"error":{"root_cause":[{"type":"illegal_argument_exception","reason":"Types**
**cannot be provided in put mapping requests, unless the include_type_name**
**parameter is set to**
**true."}],"type":"illegal_argument_exception","reason":"Types cannot be**
**provided in put mapping requests, unless the include_type_name parameter is**
**set to true."},"status":400}**
```
Could you please suggest how to fix this issue?

Look here [https://www.elastic.co/guide/en/elasticsearch/reference/current/removal-of-types.html](https://www.elastic.co/guide/en/elasticsearch/reference/current/removal-of-types.html) for the `include_type_name` parameter that is mentioned.
