Summary

When attempting to add an issue via REST API:

/rest/agile/1.0/sprint/<SPRINT_ID>/issue
with body "{"issues":["ISSUE-KEY"]}

to a sprint whose originating board has been deleted, it results to an HTTP 400 error: "The requested board cannot be viewed because it either does not exist or you do not have permission to view it."

Steps to replicate

1. Create a new Scrum board
2. Create a sprint in that board and note its ID
3. Delete the board
4. Attempt to add an issue to the sprint using the public REST API, i.e.:

    
   /rest/agile/1.0/sprint/{SPRINT_ID}/issue
   with body "{"issues":["ISSUE-KEY"]}
   

Background

Sprints are global entities that exist across many boards, even if its originating board has been deleted.

This feature works fine with server.
