JIRA.Issue.getIssueId() doesn't work for Next-Gen based projects

Question

Unfortunately API doesn't work

JIRA.Issue.getIssueId() - returns null (for issue page view/ quick issue view modal)
JIRA.Issue.getIssueKey() - returns null (for issue page view/ quick issue view modal)

Now  I found  JIRA.Issue.getIssueKey() is not work in some page, so I use Meta.get("issue-key") instead.

it's always null for me, not depends that page loaded or loading
not depends on page opened directly by link or through navigation

I have the same problem.

I found that when page has loaded, print "JIRA.Issue.getIssueKey()" in console and then i can return the correct issueKey.

Maybe the timing are different between issue page and next-gen page.
