CHANGELOG

• Moves call to redirectToSearchPageForNewUser from rootLoader to dashboardLoader.
  • Requires bringing in queryClient.ensureQueryData(queryRedeemablePolicies(...)) alongside the query to fetch enrollments to determine whether the dashboard -> search redirect is applicable based on both the enrollments but also assignments from credits_available.
• Refactors redirectToSearchPageForNewUser to accept enterpriseCourseEnrollments, and only trigger redirect from the dashboard route to search route for learners with no enrollments to display on their dashboard, in addition to the existing check on the displayed assignments.
  • Returns early if navigating from a different route (e.g., search) to the dashboard route, as this navigation was triggered by an explicit user action (e.g., clicking "Dashboard" in the header menu navigation). Otherwise, it's possible to click "Dashboard" from search route and have no change in the UI since the dashboardLoader redirects you right back to the search route you're already on).

For all changes

• Ensure adequate tests are in place (or reviewed existing tests cover changes)
• Ensure English strings are marked for translation. See documentation for more details.

Only if submitting a visual change

• Ensure to attach screenshots
• Ensure to have UX team confirm screenshots

[inform] Once the Dashboard BFF endpoint is integrated into the dashboardLoader, it will replace this queryEnterpriseCourseEnrollments.
