Custom mapping / dynamic_templates json_data


I'm trying to index a document which has a property called "json_data" (type "object").
"json_data": {"id": 1, "level": 1, "data": {another json...}}

I'm trying to create a template with dynamic_templates so that every value of "json_data" on every level (id, level, data.key1, data.key2, data.key1.subkey1... etc) to be indexed as string.

The error I get is:

"error"=>{"type"=>"mapper_parsing_exception", "reason"=>"failed to parse []", "caused_by"=>{"type"=>"illegal_state_exception", "reason"=>"Can't get text on a START_OBJECT at 1:55"}}

How can I apply dynamic_templates/mapping for all the properties/subproperties of this object? I don't know the names of the properties in advance so I need to use dynamic_templats.

"template" : "logstash-",
"mappings" : {
"default" : {
"dynamic_templates" : [
"json_data_as_strings" : {
"path_match" : "json_data.
"mapping" : {
"type" : "string",
"index": "not_analyzed",

Thank you,


Did you see 'path_match' ?
