(btw it's cool that you started with mocked hard-coded data for this to get it working, then moved it into the DB ✨)
Right now you redirect to the home page without waiting for the actual creation of the DB rows to be complete. This probably works because the redirect + loading the new page takes longer than the database queries, but this isn't guaranteed. If the query took a bit longer you'd occasionally end up on the home page without the new stuff yet.
You need to wait promises to resolve before sending any response from your server (even a redirect).
