Hi,  
Everything was working fine, i updated my logstash configuration to add one more index in output. But now i am seeing below log messages, though they are not very frequent.

[ERROR][logstash.outputs.elasticsearch] Encountered an unexpected error submitting a bulk request! Will retry. {:error\_message=\>"uninitialized constant LogStash::Outputs::ElasticSearch::Common::RETRYABLE\_CODES", :class=\>"NameError", :backtrace=\>["org/jruby/RubyModule.java:2719:in `const_missing'", "/usr/share/logstash/vendor/bundle/jruby/1.9/gems/logstash-output-elasticsearch-7.3.1-java/lib/logstash/outputs/elasticsearch/common.rb:248:in`safe\_bulk'",

Any idea why these log messages show up. I have cross checked everything relating to xpack configuration , cert, password everything looks fine.

Would appreciate any help.  
Regards,  
Amit Singh
