[Satellite6] foreman-rake foreman_tasks:export_tasks fails with NoMethodError: undefined method `state' for nil:NilClass
Environment
- Red Hat Satellite 6.2
Issue
- Creating a task-export always fails at the end with error
NoMethodError: undefined method 'state' for nil:NilClass
Resolution
This issue in the dynflow component has been fixed in Satellite 6.3 via RHSA-2018:0336.
To successfully export the task list on Satellite 6.2, will be needed to remove the tasks that are in 'planning' state and with the result 'error', with the following commands:
foreman-rake console
ForemanTasks::Task.where(:state => "planning").where(:result => "error").destroy_all
quit()
After successfully removing the problematic tasks, repeat the export command.

Root Cause
In the dynflow component, there's a bug that prevent showing plans without root_plan_step as tracked in This content is not included.BZ#1501357.
This is the condition of those tasks that are in a 'planning' state but with 'error' as result.
Diagnostic Steps
You can run a command for export_tasks with the --trace option
foreman-rake foreman_tasks:export_tasks task_search=all --trace
** Invoke foreman_tasks:export_tasks (first_time)
** Invoke environment (first_time)
** Execute environment
** Execute foreman_tasks:export_tasks

Tasks: TOP => foreman_tasks:export_tasks
To check if there are tasks in a 'planning' state and an 'error' result, you can run the following command:
su - postgres -c "psql foreman -c \"select * from foreman_tasks_tasks where state= 'planning' and result = 'error';\""
