Common Errors & Troubleshooting

404 Not Found Requesting a category or clue ID that does not exist in the database
Use /api/categories?count=100 to discover valid category IDs before querying specific ones
Empty or null answer field Some Jeopardy clues have redacted or missing answers in the source data
Check if the answer field is null or empty before displaying it, and skip or flag those clues in your app
Slow response times The free public API may have occasional latency spikes
Add a reasonable timeout (5–10 seconds) in your fetch call and display a loading state in the UI
