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'll help you fix the hydration mismatch error. Let me first read the debug logs to understand what's happening, then examine your layout file.
Now let me check if there are any client components or hooks that might be modifying the body element:
Let me search more specifically for the issue. The attributes __processed_, bis_status, and bis_frame_id are being added by browser extensions. The key fix is to suppress the hydration warning since this is coming from a browser extension, not our code:
I've fixed the hydration mismatch error. The issue was caused by browser extensions (like BIS/Bitdefender or other tracking tools) adding attributes to the <body> element after the page loads, which differ from the server-rendered HTML. By adding the suppressHydrationWarning attribute to the <body> tag, Next.js will ignore hydration mismatches for that specific element. This is the recommended approach when the mismatch is caused by browser extensions or external code that you can't control.
bây giờ tôi muốn tạo cho trang web này một chứ năng đăng nhập, nhăm lưu lại tài khoản cho lần đăng nhập sau, không cần các chức năng đăng nhập phức tạp như gửi mã otp về để đăng nhập hoặc đăng nhập từ google, yêu cầu chỉ cần người dùng tạo tài khoản và web sẽ tự động lưu tài khoản và mật khẩu cho lần đăng nhập sau
I'll help you add a login functionality to your website with account persistence. Since this is a significant feature requiring database integration and authentication, let me enter plan mode to create a comprehensive approach for your approval.
Let me first explore your project structure and check what integrations are available:
Now let me check the Supabase schema and explore the current project structure:
Let me explore more of the project structure:
Let me check the main page and components:
Let me check for the lib folder and existing types:
Now I have a complete understanding of the project. Let me write a comprehensive plan for implementing the login functionality:
