Debug: Product Search That Misuses Its API
Challenge summary
Debug a product search page that misuses its search API, then add a small feature. Each of four user reports points to a different mistake in how the component calls and reads the API.
What you'll practice
- Trace a wrong-results report back to a mismatched response field.
- Make an effect search again when its input changes.
- Stop a slow response from overwriting newer results.
- Turn a rejected request into a clear error state that the next search clears.
