Hello,

I am facing this logstash error :
logstash.inputs.tcp - An error occurred. Closing connection {:client=>"*******":59523", :exception=>#<NameError: uninitialized constant LogStash::Codecs::Telemetry::Telemetry>, :backtrace=>["org/jruby/RubyModule.java:2719:in const_missing'", "/cisco-telemetry-plugin/lib/logstash/codecs/telemetry.rb:739:in decode'", "/usr/share/logstash/vendor/bundle/jruby/1.9/gems/logstash-input-tcp-4.1.0/lib/logstash/inputs/tcp.rb:182:in handle_socket'", "/usr/share/logstash/vendor/bundle/jruby/1.9/gems/logstash-input-tcp-4.1.0/lib/logstash/inputs/tcp.rb:153:in server_connection_thread'"]}

my configuration file :
input {
tcp {
port => 5551
codec => telemetry {
mdt => true
protofiles => "/data/proto"
}
}
}
output {
elasticsearch {
hosts => "elasticsearch:9200"
index => "telemetry-gpb-%{+YYYY.MM.dd}"
}
}

One more information is that I am using this plugin with logstash 5.3.0 and it worked using json codec and PDT configuration on the router.

Best,

when I use xform flat option, it fails to generate logstash events. Raw seems to work but I need the flatten functionality.
