Map all int and long datavalues to string

Elastic Stack Elasticsearch
1

i am looking at mapping all the int/long/float/double values that elasticsearch receives to string type.

This is what i have done-

  1. Created config/mappings/_default/mapping.json
  2. Added-
    {
    "data" : {
    "dynamic_templates" : [
    {
    "string_template" : {
    "match" : "*",
    "match_mapping_type" : "int",
    "mapping" : {
    "type" : "string"
    }
    }
    }
    ]
    }
    }

ES is throwing this exception-
