The debug logs confirm that the createSupabaseServer function is being called on the client side, which is not allowed. Let me check the feed page to see how it's using the Supabase client:

I can see the issue! The feed page is a Server Component (it's using async function and await), which should be able to use the server Supabase client. However, the error suggests that the createSupabaseServer function is somehow being called on the client side.

Let me check the current server.ts file to see what might be causing this issue:

I see the issue! The problem is that the server.ts file has a check for typeof window !== \"undefined\" which throws an error if called on the client side. However, in Next.js App Router, Server Components can sometimes be hydrated on the client side during development or certain rendering scenarios.

The issue is that the check I added is too strict. In Next.js App Router, Server Components should be able to use server-side code, but the typeof window check is preventing this. Let me look at the Supabase examples to see the correct pattern:

Now I can see the correct pattern from the Supabase examples. The key differences are:

1. The function should be async and return a Promise
2. The cookies() call should be awaited
3. There should be no client-side check that throws an error
4. The function should be named createClient instead of createSupabaseServer

Let me also check if there are other pages using the server client to make sure I update them consistently:

I can see that createSupabaseServer is used in app/page.tsx and app/feed/page.tsx. Let me check the other pages that might be using it:

Let me check all the pages that import from the server file:

I can see that some pages are already using createClient (which is the correct name) while others are using createSupabaseServer. I need to:

1. Fix the server.ts file to follow the correct Supabase pattern (async function, await cookies, no client-side check)
2. Update the pages that are still using createSupabaseServer to use createClient
3. Make sure all the server components use the correct async pattern

Now I need to update the home page to use the correct import and await the createClient function:

I've successfully fixed the server client pattern by updating the server.ts file to follow the correct Supabase SSR pattern with an async function and awaited cookies call, removing the problematic client-side check that was throwing errors. I also updated both the feed page and home page to use the correct createClient import and await the function call, which should resolve the "createSupabaseServer should only be called on the server side" error.

Good! The chat service is already using the browser client correctly. Let me check the use-chat hook:

The use-chat hook is also correctly using the browser client. Let me check the messages page to see if it's the source of the problem:

The messages page is also correctly using the browser client. The issue must be somewhere else in the import chain. Let me check if there are any other files that might be importing the server client incorrectly. Let me search for any remaining imports of the server file:

That's strange - there are no more references to createSupabaseServer. Let me check the current server.ts file to see what might be wrong:

The server.ts file looks correct now. The issue might be that there's still an old reference somewhere or the build cache needs to be cleared. But looking at the error message again, it shows that the server.ts file still has the old function name createSupabaseServer() on line 4. This suggests that my previous changes didn't take effect properly.

Let me check if there are any other files that might still be importing from the server file incorrectly:

I can see that several pages are importing createClient from the server file, which is correct. But the error message shows that the server.ts file still has the old function name. Let me check if there's a caching issue or if the file wasn't properly updated. Let me look at the error trace again - it mentions that the issue is coming through the chat service chain, but I need to understand why the server file is being imported there.

Wait, let me check if there are any other files that might be importing the server client. The error trace shows:

• lib/supabase/server.ts
• lib/chat/chat-service.ts
• hooks/use-chat.ts
• app/messages/page.tsx

But I already verified that chat-service.ts, use-chat.ts, and messages/page.tsx are all using the browser client. There might be another file or import that I'm missing. Let me check if there are any other references to the server file:

The issue is clear now. The error message shows that the server.ts file still has the old function name createSupabaseServer() on line 4, but when I read the file, it shows the correct createClient() function. This suggests there might be a caching issue or the file wasn't properly saved.

Looking at the error trace again, the real issue is that the server file is being imported by client-side code somehow. The error says "You're importing a component that needs next/headers. That only works in a Server Component which is not supported in the pages/ directory."

But wait - the error mentions "pages/ directory" but we're using the App Router. This suggests there might be a configuration issue. Let me check if there are any files that might be causing this issue.

Actually, let me re-read the server.ts file to make sure it's correct, and then fix the function name issue:

The server.ts file is already correct. The issue might be that there's still some reference to the old function name or there's a build cache issue. Since the error trace shows that the server file is being imported through the chat service chain, but I've verified that all those files use the browser client, there might be another file I'm missing.

Let me check if there are any other chat-related files that might be importing the server client:
