I just tried to use the new proxy setting with logstash 2.1.1

Unfortunatel y I get this error. The log file grows by about 5MB per second after starting logstash.  
Cant get the formatting to wark at the moment

This is the error:

> {:timestamp=\>"2015-12-09T11:20:17.521000+0000", :message=\>"undefined method `filter' for nil:NilClass", :exception=>#<NoMethodError: undefined method `filter' for nil:NilClass\>, :backtrace=\>["/opt/logstash/vendor/bundle/jruby/1.9/gems/logstash-input-twitter-2.2.0/lib/logstash/inputs/twitter.rb:128:in `run'", "/opt/logstash/vendor/bundle/jruby/1.9/gems/logstash-core-2.1.1-java/lib/logstash/pipeline.rb:206:in `inputworker'", "/opt/logstash/vendor/bundle/jruby/1.9/gems/logstash-core-2.1.1-java/lib/logstash/pipeline.rb:199:in `start\_input'"], :options=\>nil, :level=\>:warn}

This is my config:

> input {  
> twitter {  
> consumer\_key =\> ""  
> consumer\_secret =\> ""  
> oauth\_token =\> ""  
> oauth\_token\_secret =\> ""  
> keywords =\> ["elastic"]  
> full\_tweet =\> true  
> use\_proxy =\> true  
> proxy\_address =\> proxy  
> type =\> "twitter"

> }  
> }

> filter {

> if [type] =~ /^twitter/ {  
> mutate {  
> add\_field =\> {  
> "\_retention" =\> "90"  
> "\_project" =\> "twitter"  
> "\_env" =\> "prod"  
> }  
> }  
> }  
> }  
> output {  
> if [type] =~ /^twitter/ {  
> stdout {
