Error when i try to crowle a secured mail box with IMAP plugin in logstash

[amine]

Hi everyone;

I try to crowle a secured mail box with IMAP plugin in logstash with this configuration :

imap {
        host => "mydom.mydomain.com"
        user => "test-search@mydomain.com"
        password => "myPass`Preformatted text`word"
        port => 993
        secure => true
        check_interval => 1
   
 }

I have this error :

16:11:04.752 [[main]<imap] ERROR logstash.pipeline - A plugin had an unrecoverable error. Will restart this plugin.
  Plugin: <LogStash::Inputs::IMAP host=>"", user=>"", password=><password>,

ue, charset=>"UTF-8">, verify_cert=>true, folder=>"INBOX", fetch_count=>50, lowercase_headers=>true, delete=>false, expu

    user => "test-search@mydomain.com"
    password => "myPassword"
    port => 143
    secure => false

}
