I tried yum remove logstash and reinstalling by puppet agent -t, but still same error.
dec 16 11:48:18 logstash[8145]: [FATAL] 2021-12-16 11:48:18.130 [main] Logstash - Logstash was unable to start due to an unexpected Gemfile change.
dec 16 11:48:18 logstash[8145]: If you are a user, this is a bug.
dec 16 11:48:18 logstash[8145]: If you are a logstash developer, please try restarting logstash with the `--enable-local-plugin-development` flag set.
How can there be "Unexpected Gemfile change", if it is a fresh install?
