FE: Display work item epic in legacy issue's sidebar
When visiting a legacy issue that has a work item epic assigned as a parent, this needs to be displayed in the same way we display the legacy epic, in the issue's right sidebar.
We currently fetch the legacy epic using project_issue_epic.mutation.graphql but if not present we’ll need to check if a work item parent is present instead.
This new query will have to search for a parent using the issue’s id as the work item global ID, for example:
query getParent {
workItem(id: "gid://gitlab/WorkItem/<LEGACY_ISSUE_ID>") {
widgets {
... on WorkItemWidgetHierarchy {
parent {
id
title
webUrl
}
}
}
}
}
For removing the epic we'll also have to use a different query if the epic is a work item, for example:
mutation workItemUpdate {
workItemUpdate(input: {id: "gid://gitlab/WorkItem/<LEGACY_ISSUE_ID>", hierarchyWidget: {parentId: null }}) {
errors
}
}
Note: To avoid making two requests we can check if the issue has a work item parent. See #423984 (comment 1570054271)
