Unable to create elasticsearch indices for json file

I am having this json file for which I am using .conf file to parse it into elasticsearch indices but I am getting error.
My .conf file is :
input {
file {
codec => json
path => ["/home/2017.09.04.json"]
start_position => "beginning"
sincedb_path => "/dev/null"
}
}
filter {
json {
source => "message"
}
}
output {

stdout { codec => rubydebug}

     elasticsearch
                  { hosts => ["http://192.168.0.178:9200"]
                   index => "syslog"
                 # codec => "json_lines"
               }
   } 

and I am getting an error saying
"[WARN ] 2019-09-11 15:39:24.960 [[main]>worker8] elasticsearch - Could not index event to Elasticsearch. {:status=>400, :action=>["index", {:_id=>nil, :_index=>"syslog", :_type=>"_doc", :routing=>nil}, #LogStash::Event:0x58a57c7b], :response=>{"index"=>{"_index"=>"syslog", "_type"=>"_doc", "_id"=>"jWPMH20BWRLyyJYol9Ib", "status"=>400, "error"=>{"type"=>"mapper_parsing_exception", "reason"=>"Field [_type] is a metadata field and cannot be added inside a document. Use the index API request parameters."}}}}"
Although when I use stdout => rubydebug
I get an output saying:
