This PR https://github.com/openedx/frontend-app-admin-portal/pull/1087/files#diff-89082fcf3fbc9b339141578405314256fc4f1ae0210dab880414add817619ef7 pulls from the learner view, not the admin view. So it tries to fetch only the transactions associated with the requesting user. We want the admin-portal to pull from the admin view.
