Hi guys, I have the next error on a ruby filter. I'd really appreciate any suggest [2021-04-16T11:28:06,202][ERROR][logstash.filters.ruby ][main-postilion-pipeline][87afa373e1d0191b4f869238d2908162c237ad31fe6074ec0a41fc36d14eb8fa] Ruby exception occurred: undefined method `size' for nil:NilClas…

That suggests that one of those fields does not exist. Change event.set('msg1Lenght', event.get('msg-1').size) to msg-1 = event.get('msg-1') if msg-1 event.set('msg1Lenght', msg-1.size) else event.set('msg1Lenght', 0) end Likewise for msg-2
