couchdb_changes errors with elasticsearch-5.4.0/logstash-5.4.0

[jitendranair]

Product Version:
Linux: Scientific Linux release 6.9 (Carbon)
ElasticSearch: 5.4.0
Logstash: 5.4.0

NOTE:
I switched to elasticsearch-2.4.5/logstash-2.4.1, things work and I do see couchdb docs being indexed.

Error:

[jordansissel]

It looks like this plugin is not compatible with Logstash 5.x

[jitendranair]

Thanks for the info @jordansissel.Then I would stick to the stable penultimate major series 2.x for elasticsearch and logstash.
