[JIRA]: Create new issue > search for assignee fails

[jeremyfiel]

Describe the bug
Using atlascode, when creating a new issue the assignee search fails to return any results.

To Reproduce
Steps to reproduce the behavior:

1. Create new issue
2. type a name to search to add an assignee to the ticket
3. output gives a 404

i also queried the endpoint with a quick nodejs test and the error is for issueKey=null no longer exists

{ errorMessages: [ 'The issue no longer exists.' ], errors: {} }
