Migration JIRA to Redmine
First of all, I have to say that I have never dealt with Ruby and Rails before:
I need to migrate Jira to Redmine. In my attempt with "migrate_jira.rake" the rake always breaks when reading issues:
1. first it reads all users => works fine
2. then it reads the first project => works fine
3. then it reads the first issue => abort
NoMethodError: undefined method `each' for nil:NilClass
/home/hga/redmine/lib/tasks/migrate_jira.rake:575:in `block (3 levels) in <top (required)>'
/home/hga/redmine/lib/tasks/migrate_jira.rake:573:in `block (2 levels) in <top (required)>'
/home/hga/.rvm/gems/ruby-2.6.8/gems/rake-13.0.6/exe/rake:27:in `<top (required)>'
Tasks: TOP => jira_migration:do_all_migrations => jira_migration:migrate_issues
(See full trace by running task with --trace)
I hope someone can give me a tip on how to make it work.
Thank you in advance
I forgot to say that I work with Redmine 4.2.3 in WLS2 Ubuntu 20.04
