Failed action with response of 500, dropping action Logstash1.5.4

Hi everybody, im newbie and i try use logstash, elasticsearch to
Search in my Web. One error appear and i dont know how to fix it.
Pls help me , thanks you!
i tried config file .conf look like this ,it work normal , my databse appear in my plugin /head

file: simple-out.conf

input {
jdbc {
jdbc_connection_string => "jdbc:postgresql://localhost:5432/Test"
jdbc_user => "postgres"
jdbc_password =>"lovely19"
jdbc_validate_connection => true
jdbc_driver_library => "/home/ngocpt/Downloads/postgresql-9.4-1202.jdbc4.jar"
jdbc_driver_class => "org.postgresql.Driver"
statement => "SELECT * from users"
}
}
output {
elasticsearch {
protocol => http
index => "users"
document_type => "user"
document_id => "%{id}"
host => "localhost"
}
}

But after i tried mapping one field with analyzer before run logstash index database, i get error.
my mapping look like this:
curl -XPUT "http://localhost:9200/users/" -d'
{
"mappings": {
"user": {
"properties": {
"password" : {
"analyzer" : "vi_analyzer",
"type" : "string"
},
"user_name" : {
"analyzer" : "vi_analyzer",
"type" : "string"
}
}
}
}
}'

Here is my error

Thanks for your help

The Elasticsearch logs probably contain additional clues.

maybe error in analyzer ~~
i use elastic 1.7.3 , and analyzer sp 1.7+...
