I’m using logstash-oss version 7.16.2 and receiving multiple errors where it’s either undefined method accept’ for nil:NilClassorInvalid FieldReference .` Not sure what is going on. My setup is filebeat → logstash → os and want to continue with this setup. I have different shapes of the logs and sending them to different indices based on tags (which is on the filebeat.conf). I’m not sure if others are having the same issue but this is causing logs not being sent to opensearch.
