Logstash Mongodb output plugin is not converting jdbc (Oracle) NUMBER (32,8) column to goecode latitude data

Anyone know solution of this: Error: exception=>#<NoMethodError: undefined method `bson_type' for #BigDecimal:211e7bb1,'0.32819557E2',8(12)>

There's not really much to go on here, please provide more information.

What is your config?
What version are you running?
What is the full error?

I got the answer. I have used filter for that.

filter {
	mutate {
	 convert => { "LATITUDE" => "float" }
