I have a conditional IF statement to only output if the tag [uid] == "0",
but the statement always executes to false, unless I replace [uid] with [message] which defeats the purpose of the conditional.

#my very simple pattern: UID uid=(?<uid>%{NUMBER})
output {
if [uid] == "0" {
stdout { debug => true }
}
}

Any help would be greatly appreciated.

thanks!
