We use logstash 5.4.1.  
Following the example here: [https://qbox.io/blog/indexing-emails-to-elasticsearch-logstash-imap](https://qbox.io/blog/indexing-emails-to-elasticsearch-logstash-imap), I got this error:  
[2018-01-11T14:22:38,062][ERROR][logstash.pipeline] A plugin had an unrecoverable error. Will restart this plugin.  
Plugin: \<LogStash::Inputs::IMAP host=\>"[outlook.xxx.com](http://outlook.xxx.com)", password=\>, user=\>"me@xxx.com", port=\>993, check\_interval=\>10, folder=\>"Inbox", secure=\>false, id=\>"7added54a47768e563c82563e5a6200xxxyy", enable\_metric=\>true, codec=\>\<LogStash::Codecs::Plain id=\>"plain\_8950870f-7b53-47f2-9340-309df76d96563", enable\_metric=\>true, charset=\>"UTF-8"\>, verify\_cert=\>true, fetch\_count=\>50, lowercase\_headers=\>true, delete=\>false, expunge=\>false, strip\_attachments=\>false, content\_type=\>"text/plain"\>  
Error: undefined method `name' for nil:NilClass

Any idea what might be the problem here? Thanks.
