elasticsearch7.3修改fielddata=true时报错Types cannot be provided in put mapping requests, unless the include_type_name parameter is set to true

报错如下：

{
  "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
}

原因是由于写法是低版本的elasticsearch的，高版本要求传入一个include_type_name参数，值为true。所以加上一个参数即可。如下：

PUT /test_index/_mapping/product?include_type_name=true

{

....

}
