Certainly, I'll revert the ComplaintForm component back to its previous version without the 'use client' directive. Let's do this step-by-step:

This reverts the ComplaintForm component to its previous version without the 'use client' directive. However, it's important to note that this may reintroduce the build error we encountered earlier.

To resolve this issue without adding 'use client', we have two options:

1. Move the ComplaintForm component to a client component file (e.g., create a new file app/components/client/ComplaintForm.tsx) and import it from there.
2. Use the dynamic import with ssr: false option in the parent component where ComplaintForm is used.

Let's implement the second option by updating the DashboardPage component:

This change dynamically imports the ComplaintForm component with server-side rendering disabled, which should resolve the build error while keeping the ComplaintForm component in its original location and without the 'use client' directive.

These modifications should revert the ComplaintForm to its previous state and resolve the build error. The component will now be client-side rendered, allowing it to use React hooks without the 'use client' directive.

I understand the error. Let's review and revise the code to address this issue. The error suggests that we're trying to use the split function on something that isn't a string in our login route handler.

Let's revise the code in both the login route handler and the LoginForm component:

These changes should address the error you encountered. Here's what we've done:

1. In the login route handler (app/api/login/route.ts), we've ensured that we're properly parsing the request body using await request.json(). This should prevent any issues with trying to access properties that don't exist.
2. In the LoginForm component (app/components/LoginForm.tsx), we've added error handling around the fetch call and made sure we're sending the correct data in the request body.
3. We've also added some basic error handling and user feedback in case of login failures.

These modifications should resolve the TypeError you were experiencing. The login process should now work correctly, handling both regular user and admin logins appropriately.
