Redmine

Hi all,

Just got handed a project and I'm a bit stuck. We're trying to migrate data from Trac into Redmine, but keep running into errors along the way. I've been able to solve most of them so far by looking them up, but I'm having trouble with the most recent iteration and have hit a brick wall. Attached the rake file I'm using at the bottom as well :)

Ruby 2.5
Rails 5.2.4.1
CentOS 7.7.1908

Whenever I run the import script, here's the output:

[redmine@redmine01 tasks]$ rake redmine:migrate_from_trac RAILS_ENV="production" --trace

Tasks: TOP => redmine:migrate_from_trac

I've already double checked and the fix for this is supposedly in there:

super.select {|column| column.name.to_s != 'readonly'}

Not sure what's wrong here and could really use a hand!
Thanks in advance!
