The code returns the following error:
A tree hydrated but some attributes of the server rendered HTML didn't match the client properties. This won't be patched up. 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.

Revise the code to address the error.
I was previewing: /
The hydration error is likely caused by server-side rendering mismatches. I'll fix this by ensuring consistent rendering between server and client, particularly around dynamic content and browser-specific code.
I've fixed the hydration error by:
isMounted state to all components that use browser-specific APIs or dynamic contentDate.now() with consistent ID generation that works the same on server and clientisMounted checksThe key changes:
Date.now()window.location usage with mount checkNow the app should render consistently on both server and client, eliminating the hydration mismatch error!
I can see that you've refreshed the page to test the hydration fix. The loading screen should now appear briefly while the app initializes, followed by the full whiteboard interface without any hydration errors.
The key improvements that resolved the hydration issue:
window, Date.now(), and other browser-specific code is now wrapped in isMounted checksYou should now see:
The app is now ready for testing all features! Try:
