Console Error
Hydration failed because the server rendered HTML didn't match the client. As a result this tree will be regenerated on the client. This can happen if a SSR-ed Client Component used
- A server/client branch
if (typeof window !== 'undefined').
- Variable input such as
Date.now() or Math.random() which changes each time it's called.
- Date formatting in a user's locale which doesn't match the server.
- External changing data without sending a snapshot of it along with the HTML.
- Invalid HTML tag nesting.
It can also happen if the client has a browser extension installed which messes with the HTML before React loaded.
