At moment, i do so:
1) Perform request, like:
jira.Issues.GetIssuesAsync("list_issue_keys")
2) Iterate result and check custom field "Epic Link"
3) If custom field "Epic Link" is exists, then performs second request
jira.Issues.GetIssue("epic_link")and extract it "Summary".
If try extract custome field "Epic Name" directly in result of first request, then thrown exception. Field does not exists.
How wrote right? It possible per one request?
