Error when trying to associate Issue Type Scheme to Project

[Qi Xun Yeo]

Hi, 

I am trying to associate an issue type scheme to a project but was met with the following error: 

• There are 2 sub-tasks that will be affected by this change. You must have at least one valid sub-task issue type.
  
  

How should I proceed with this?

Either

• Search for the sub-tasks in the project (issuetype in subtaskissuetypes() should do it) and use "move" to change them from sub-tasks to standard issue types
• Add at least one sub-task type to your new issue type scheme

Thank you!
