Setting a default value for missing fields during indexing or reindexing

I am trying to create an elastic search mapping where during indexing of data if a field is missing it should add some default value.

PUT my_index

  "mappings": {
    "_doc": {
      "properties": {
        "status_code": {
          "type": "keyword"
        "response": {
          "type": "string"

PUT my_index/doc/1

{ "statuscode": "200" }

So, as in the above example response field is missing , is it possible to add some default value during indexing for response.?
