Dynamic Template convert JSON object to Text

[psteh]

Is it possible to convert JSON object to Text using Dynamic Template?
My aim is to have all fields in this object property to be Text

I am not using Logstash, this is from AWS Cloudwatch log to AWS Elasticsearch Service.

I have here part of my template

"bindings": {
	"path_match": "properties.bindings.*",
	"match_mapping_type": "*",
	"match": "*",
	"mapping": {
		"type": "text",
		"fields": {
			"keyword": {
				"ignore_above": 256,
				"type": "keyword"
			}
		}
	}
}

I have gotten error on some fields for example

Could not index event to Elasticsearch. {:status=>400, :action=>["index", {:_id=>nil, :_index=>"cwl-2020.05.22", :_type=>"_doc", :routing=>nil}, #<LogStash::Event:0x58ca9f05>], :response=>{"index"=>{"_index"=>"cwl-2020.05.22", "_type"=>"_doc", "_id"=>"RG0jVHIBuw9XhmjONWGk", "status"=>400, "error"=>{"type"=>"mapper_parsing_exception", "reason"=>"failed to parse field [properties.bindings.2] of type [text] in document with id 'RG0jVHIBuw9XhmjONWGk'. Preview of field's value: '{date=2020-05-22 09:10:32.207187, timezone=Asia/Kuala_Lumpur, timezone_type=3}'", "caused_by"=>{"type"=>"illegal_state_exception", "reason"=>"Can't get text on a START_OBJECT at 1:6223"}}}}}

Solved with using enabled mapping
I don't quite understand what it does, but I got the result I wanted.

"bindings": {
    "path_match": "properties.bindings.*",
    "match_mapping_type": "*",
    "match": "*",
    "mapping": {
        "type": "object",
        "enabled": false
    }
 }
