Hi, This is my Dockerfile. ```auto FROM docker.elastic.co/logstash/logstash:6.2.2 ENV SSL_CERT_FILE /opt/logstash/logstash-core/lib/logstash/certs/cacert.pem RUN logstash-plugin install logstash-input-google_pubsub ``` This is my logstash conf. ```auto input { google_pubsub { project_id => "project" topic => "topic" subscription => "logstash-sub" json_key_file => "/mnt/sa.json" } } output { stdout { codec => rubydebug } } ``` While logstash is running, the error message keeps on flushing out. It stills receive published message if I published a test message. The error logs: ```auto [2018-02-22T12:11:33,707][INFO][logstash.runner] Starting Logstash {"logstash.version"=>"6.2.2"} [2018-02-22T12:11:34,578][INFO][logstash.agent] Successfully started Logstash API endpoint {:port=>9600} [2018-02-22T12:11:41,419][INFO][logstash.pipeline] Starting pipeline {:pipeline_id=>"main", "pipeline.workers"=>2, "pipeline.batch.size"=>125, "pipeline.batch.delay"=>50} [2018-02-22T12:11:45,937][INFO][logstash.inputs.googlepubsub] Client authorizataion with JSON key ready [2018-02-22T12:11:45,978][INFO][logstash.pipeline] Pipeline started succesfully {:pipeline_id=>"main", :thread=>"#"} [2018-02-22T12:11:46,349][INFO][logstash.agent] Pipelines running {:count=>1, :pipelines=>["main"]} [2018-02-22T12:12:11,039][ERROR][logstash.inputs.googlepubsub] Error 400: You have not specified an ack ID in the request.

For reference, this issue is in discussion in the plugin's github repo. > As message subscription is still fine, I just ignore those overwhelming error logs. ---
