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:NilClass

Here's my pipeline filter

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
