getDerivedStateFromProps is not called

make sure you have the right versions of both react and react-dom in your package.json:

"react": "^16.3.1","react-dom": "^16.3.1"

reactjs next.js react-16

I see that support for this hook was patched in version - 6.0.0-canary.2 of next.JS. So I'm guessing you use an older version.
