undefined method `downcase' for nil:NilClass (NoMethodError)

[hsanson]

Running this tool I get this error:

Appears to be related to Issue #2, and hopefully fixed now. Try

gem update little_red_flag

then run again and let me know?

Unfortunately not solved with 0.1.3:

Looking at the trace the problem seems to be that ssltype is nil:

21: imap = Net::IMAP.new(host, port: port, ssl: (ssltype.downcase == 'imaps'))

And I do have an IMAP account that does not use IMAPS:

IMAPAccount [email protected]
Host mail.email.net
User [email protected]
Pass secretPassWord
UseIMAPS no
RequireSSL no

I am trying to create the smallest config file that reproduces the issue but when I delete other parts of the config I get a different error:

/var/lib/gems/2.3.0/gems/little_red_flag-0.1.3/lib/little_red_flag/mail_agent/mbsync/config.rb:187:in `block in link_group_channels': undefined method `map!' for "xxxxx-email-inbox":String (NoMethodError)

        from /usr/local/bin/littleredflag:23:in `<main>'

BTW: Would be nice to have a flag option to use a different .mbsyncrc file so I do not have to modify my main configuration to debug this.

v0.1.4 should check that ssltype is not nil before trying to apply the #downcase method.

Three version bumps in one day. How embarrassing. The code is a bit of a mess right now tbh, but I intend to give it a hearty refactoring when I get some time to hunker down with it again.

Thanks for your help.

First time I have had an issue solved within one hour of reporting!!.

Last fix seems to be working, Thanks.
