Error with railsexpress ruby

It sends email to some users, but not all...

I have resolved it by adding...

def active?
    self.status == STATUS_ACTIVE
  end

to group.rb model...

Requested this, but... https://www.redmine.org/issues/27510

I have similiar problem. I've added your code into group.rb, but still I have error like this:

rake aborted!
NoMethodError: undefined method active?' for #<Group:0x0000556f0add2a60> Did you mean? acts_like? /opt/bitnami/apps/redmine/htdocs/plugins/redmine_reminder/lib/tasks/reminder_all.rake:33:in block (3 levels) in <top (required)>'

Tasks: TOP => redmine:send_reminders_all
(See full trace by running task with --trace)

Of course after adding the code I've migrated plugins end restarted apache.
