Ranking creation fails silently after required visible fields are entered #39

Area

Rankings / Create ranking

Issue:

Entering a name and URL and then selecting Create ranking leaves the user on the same page. No inline error, toast, focus change, or other feedback explains why submission failed. The form presents its date range as unlabeled optional-looking fields, so the blocked requirement is not discoverable from the failed state.

Repro Steps

1. Sign in and open Dev League → Create a ranking (create-ranking.png).
2. Enter QA Browser Ranking for Name and qa-browser-ranking for URL.
3. Click Create ranking.
4. Observe the unchanged form with entered values and no error (ranking-created.png).

Expected

Either create the ranking or give a clear, field-level validation message explaining what still needs input.
