Return Indirectly Related Stories When Inputting Initiative

[Lawrence McQuaid]

Hello!

I am currently working on a query that when inputting an Initiative ID, the user is able to see all of the Stories associated with the Epics associated with said Initiative:

Initiative ID (input) -> Epics -> Stories (output)

I utilize the following query to get all of the Epic ID's associated to an Initiative ID:

issue in linkedAllIssues(XX-XX) AND type = Epic

I have been trying to utilize linkedAllIssues("") with an AND function including childIssuesOf(""), though have not been successful. An example query and return message outlining that no information was returned, is outlined below:

issue in childIssuesOf("issue in linkedAllIssues(XX-XX) AND type = Epic")

"Unable to find an issue with matching key issue in linkedAllIssues(XX-XX) AND type = Epic"

Has anyone ran into this issue before, and solved it by utilizing only a JQL query?
