I'm getting an error only when persistent queues are enabled.
I enabled persistent queues with the following settings:
queue.type: persisted path.queue: /etc/logstash/data/queue queue.max_bytes: 8gb queue.checkpoint.writes: 1
I'm getting this error:
[2017-03-17T17:52:00,212][ERROR][logstash.filters.ruby ] Ruby exception occurred: wrong argument type String (expected LogStash::Timestamp)
Are there any known issues with persistent queues and the ruby filter ?
