Hello everyone, 1. I am using dead letter queue and based on some filters I want to index all the processed events to ES. 2. In output section of dlq I am using, **index =\> "index-prod-l%{+YYYYMMdd}**" to create dynamic indices based on date and time. 3. but when I ran this I got error =\> [**FATAL**][logstash.runner] An unexpected error occurred! {:error=\>#\< **LogStash::Error: timestamp field is missing** \>, :backtrace=\>["org/logstash/ext/JrubyEventExtLibrary.java:177:in `sprintf'", ... and hence logstash got terminated. 4. At the same time same index-name logic works with **main** pipeline and creates new indices on ES on daily basis. 5. and when I change index name logic as **index =\> "index-1"** in dlq conf, the index got created on ES and processed events also got indexed on ES. 6. so is there a way to check if @timestamp is present or not and if not is there a way to add it in the event? 7. logstash version =\> 6.5.4, elasticsearch version =\> 6.6.0. and kibana version =\> 6.6.1 Thanks in advance! ---
