Unable to Create Sub-Tasks in Jira API

[JD Lobue]

I am using teams' Jira app plugin to pull in Jira work for a team and I'm not seeing the ability to create sub-tasks. Can this be done? Is there something I need to change in my jira configuration? Thanks.

Jira API message:

Some issue types are unavailable due to incompatible field configuration and/or workflow associations.

Yes, it's telling you exactly what the pronlem is.  This project is not configured to allow you to create sub-tasks.  Your admins can change that.

Thanks, Nic. I am an admin, yet do not know how to do this. Can you help? Thanks

It's not that obvious (there's a lot in Jira, we can't be expected to know where everything is - I've been with it getting on for 2 decades and still can't find half the admin stuff without having to think or search).

Go to the project, and look at its settings.

For Classic projects, head for the "issue type scheme" to add sub-tasks (check how many projects you may affect in the header though)

For Next-Gen projects, head for just "issue types" and check the bottom of the list of current ones, there should be "add sub-task" in there.

I have Sub-Tasks added as an issue type in the scheme, and they are still not exposed in the API for create issue. Is there something else I need to do?

[Nic Brough -Adaptavist-]

What is the error message you are getting from the attempt to create a sub-task?  And how are you doing it?

[JD Lobue]

It simply is not a part of the dropdown as depicted in the Jira API posted above. No error message. Are sub-tasks just not exposed? Can this be added?
