NoMethodError: undefined method `find_or_create_by_name'

Hi. I do:

$ RAILS_ENV=production bin/rake jira_migration:migrate_issue_types      
[...]
Migrated Users
rake aborted!
NoMethodError: undefined method `find_or_create_by_name' for #<Class:0x00000004dad230>

Tasks: TOP => jira_migration:migrate_issue_types
(See full trace by running task with --trace)
$ 

My map_jira_to_redmine.yml looks like:

types:
  Bug: Bug
  New Feature: Feature
  Task: Task
[...]

Bug, Feature and Task trackers exist in Redmine, but I get this error.
jira_migration:test_all_migrations passes OK.

No clue, where to look next. Trace was not helpful.
