I am getting the below error:

[2023-10-18T17:37:02,573][FATAL][logstash.runner] An unexpected error occurred! {:error=\>#\<ArgumentError: wrong number of arguments (given 2, expected 0..1)\>, :backtrace=\>["/usr/share/logstash/vendor/bundle/jruby/3.1.0/gems/i18n-1.14.1/lib/i18n.rb:210:in `translate'", "/usr/share/logstash/logstash-core/lib/logstash/java_pipeline.rb:427:in `inputworker'", "/usr/share/logstash/logstash-core/lib/logstash/java\_pipeline.rb:405:in `block in start\_input'"]}

PFB, logstash configuration of the same:

Over at github there is an open [issue](https://github.com/elastic/logstash/issues/15451) for this, although that is perhaps a duplicate of another recent [issue](https://github.com/elastic/logstash/issues/15407).

Might be fixed by downgrading to 8.9.x or even 8.8.x.

May be related to the JRuby update in 8.10. The i18n code has [extensive comments](https://github.com/ruby-i18n/i18n/blob/7cf09474b77fd41e65d979134b0525f67cf371b0/lib/i18n.rb#L197) about how calls to the .t alias will fail in different versions of ruby. The call is [here](https://github.com/elastic/logstash/blob/6046402a3582eb813cfdc9c3ed5dca89e961ed6e/logstash-core/lib/logstash/java_pipeline.rb#L427).

Dowgrading logstash to 8.9.x worked for me. Thanks

Can you try to remove/comment the line:  
`# host => "10.5.68.149, 10.5.68.150"`

According to [the doc](https://www.elastic.co/guide/en/logstash/current/plugins-inputs-beats.html#plugins-inputs-beats-host), should be a string, not an array.
