Serialization/mapping errors

These kinds of errors happen due to JSON serialization issues or if you are trying to index an integer into a string field. For example, you are trying to index a person document, and the mapping for the age field is set to an integer. If you try to index one as the age field as shown next, you will see a mapping error:

The response to the preceding request is shown next:

{   "error": {     "root_cause": [       {         "type": "mapper_parsing_exception",         "reason": "failed to parse [age]"       }     ],     "type": "mapper_parsing_exception",     "reason": "failed to parse [age]",     "caused_by": {       "type": ...
