Cannot read property 'bodyEmitter' of undefined

[natiz]

I've been having some issues the listener, where it sometimes gets disconnected. I've put up a retry mechanism, where upon 'server:disconnected' it retries to connect (.start() command) every 1 minute, but then I see the logs stacked with the following error (seems intermittent):

info: IMAP disconnected, retrying... info: Restarting IMAP connection. [retries=1] info: Restarting IMAP connection. [retries=2] info: Restarting IMAP connection. [retries=3] info: Restarting IMAP connection. [retries=4] error: uncaughtException: Cannot read property 'bodyEmitter' of undefined stack: [ 'TypeError: Cannot read property 'bodyEmitter' of undefined', ' at Connection._resTagged (../node_modules/mail-listener2/node_modules/imap/lib/Connection.js:1484:10)', ' at Parser.

What could cause this? should I be retrying differently? recreate MailListener object?
