Looking at the method signatures for getIssueObject() in this resource, I see that it can be passed either a Long or a String. If it's a Long, it should be the issue ID; if it's a String, it should be the issue key. It looks like you are passing the ID as a String (and hence the method looks for an issue with that key); try passing it instead as a Long, i.e.

def issue = issueManager.getIssueObject(issueId)
