Issues with this Issue Type must be created in the same project as the parent - NOT a subtask

[Cole Marsteller]

I'm getting this error while working with the REST API when attempting to create a TASK or STORY type issue and link it back to an epic in another project.

Is this expected?

I'm also noticing that in the UI, the parent dropdown doesn't autocomplete/automatically load epics outside of the project I am in. However, if I specify an epic key exactly, e.g. EPIC-519, it appears and it DOES allow me to save it.

So it appears the restriction is only on the API side.

Hello @Cole Marsteller 

Welcome to the Atlassian community.

When using the API what is the Type of the project where you are trying to create the issues? Is it a Team Managed project? And when you are setting the parent through the UI are you trying that in the same project you are targeting withe the API?

Attempted to set the `parent` field on both a Task and Story type issue from Project A to an Epic in Project B.

Both projects are company managed

Correct

Can you tell us the API Endpoint you are using and the content that you are sending specifically to set the issue parent?
