Hi,  
I have created an index in elasticsearch 7.6. The mapping is as follows:

```auto
{
  "employee_202005011710": {
    "mappings": {
      "properties": {
        "employee": {
          "properties": {
            "name": {
              "type": "text",
              "fields": {
                "raw": {
                  "type": "keyword"
                }
              },
              "analyzer": "simple"
            },
            "department": {
              "type": "text",
              "fields": {
                "raw": {
                  "type": "keyword"
                }
              },
              "analyzer": "simple"
            },
            "designation": {
              "type": "text",
              "fields": {
                "raw": {
                  "type": "keyword"
                }
              },
              "analyzer": "simple"
            }
          }
        }
      }
    }
  }
}

```

I have a python code that performs a bulk insert into this index. However I am getting the following error when the insert is performed:

```auto
{"_index":"employee_202005011710","_type":"employee","_id":"lZWw0XEBHjlZM_lHtKQq","status":400,"error":{"type":"illegal_argument_exception","reason":"Rejecting mapping update to [employee_202005011710] as the final mapping would have more than 1 type: [_doc, employee]"}}}

```

Can someone tell me what is causing this exception?

Hello @Ketan_Chachad

If the index `employee_202005011710` has been created on Elasticsearch 7.x, the default document type is `_doc`.

You're indexing a document providing `employee` as value of the `_type`.

Since [Elasticsearch 6.x it is no more possible to have multiple types within the same index](https://www.elastic.co/guide/en/elasticsearch/reference/7.x/removal-of-types.html) and since Elasticsearch 7.x providing the document type is deprecated and it is no more required (it defaults to `_doc`).

There are 2 ways to solve this:

1. Delete the index and put the the mapping with the parameter `include_type_name` and continue indexing the documents using `employee` as document `_type`

```auto
PUT employee_202005011710?include_type_name
{
  "mappings": {
    "employee": { # this is the type name
      "properties": {
        "employee": { # this is the name of a field
      }
    }
  }
}

```

1. Just change the indexing settings on your Python code to no more provide a custom document type or force it to `_doc`.

* * *

As a side note, I notice the mapping has a `employee` property at the root, which means all fields will be within the key `employee`.

Thanks a lot @Luca_Belluccini for your solutions!  
I tried both solutions and they worked.  
However when I created a new index with include\_type\_name=true, I got the following message:  
`#! Deprecation: [types removal] Using include_type_name in create index requests is deprecated. The parameter will be removed in the next major version.`  
Does this mean that going forward solution #2 (using \_doc or no type) is the future ready solution?

Exactly, not providing the `_doc` is the future proof solution.
