The issue is that the `useEffect` dependency array includes `options`, which is a new object on every render because it's created inside the component. This causes the effect to run on every render.
To fix this, we should depend on `userId` instead, since that's the only value that actually changes and triggers a necessary re-fetch.
Here's the change:
```diff
- }, [options]);
+ }, [userId]);
```
This ensures the effect only runs when the `userId` changes, not on every render. Let's make this change.
