Footer cannot display stars and forks

The star and fork in Footer cannot be displayed like the demo(https://v4.brittanychiang.com/) in my deployment.

This is the demo:

And this is my deployment:

Maybe the useEffect function in src/components/footer.js is not working properly.

But I'm not a professional front-end developer, it's just my guess, haha:)

My environment is as follows:

1. Ubuntu 20.04
2. Gatsby CLI version: 5.13.3
3. Gatsby version: 3.15.0
4. Node: 20.9.0
