-### Task 1: Fix `Get Series Episodes` API Test
-**Test Result:** FAIL — `ConnectionError: ('Connection aborted.', ConnectionResetError(104, 'Connection reset by peer'))`
-**File:** `tests/robot/api/anime.robot`
-**Instructions:**
-The test adds a series and then calls `Get Series Details` to retrieve episodes. During the run, the connection was reset by the server. Investigate whether the server crashes when fetching episodes for a newly added series. Check `src/server/api/anime.py` and `src/server/services/anime_service.py` for the episode retrieval endpoint. Ensure the endpoint handles series with empty episode lists gracefully and does not crash. Add error handling or fix the underlying crash.
