I have json data that has a "product\_ref" field (mapped as text) that can take these values as an example:

"product\_ref": "N/A"  
"product\_ref": "90323"  
"product\_ref": "SN3005"  
"product\_ref": "2015-05-23"

When pushing the data to the index i get a mapping error:

{"error":{"root\_cause":[{"type":"illegal\_argument\_exception","reason":"mapper [root.product\_ref] of different type, current\_type [date], merged\_type [text]"}],"type":"illegal\_argument\_exception","reason":"mapper [root.product\_ref] of different type, current\_type [date], merged\_type [text]"},"status":400}

How to fix this?

Set the mapping before indexing the first document.

If already set the mapping as follows:

```
{
    "mappings" : {
        "root" : {
            "properties" : {
                "product_seller" : {
                    "type" : "text"
                },
                "product_category" : {
                    "type" : "text"
                },
                "product_name" : {
                    "type" : "text"
                },
                "product_ref" : {
                    "type" : "text"
                },
                "product_brand" : {
                    "type" : "text"
                },
                "product_price" : {
                    "type" : "long"
                },
                "product_link" : {
                    "type" : "text"
                }
            }
        }
    }
}
```

Really?

Can you tell me what is the output of:

```
GET YOURINDEXNAME/_mapping

```

Also an exact document. I think your document has a `root` object in it which either should not be there or at least does not comply with the mapping.

And all formatted as explained in [About the Elasticsearch category](https://discuss.elastic.co/t/about-the-elasticsearch-category/21).
