[WARN ][logstash.codecs.jsonlines] JSON parse error, original data now in message field {:error=>#<LogStash::Json::ParserError: No message available>, :data=>"null\r"}

That is telling you that it received a message containing "null\r", which will have resulted in a _jsonparsefailure tag being added and the event being dropped.
