I’ve recently started diving into Next.js, but I’ve hit a roadblock while working on the logout functionality. Despite researching similar issues, I’m still unable to resolve the error I’m encountering. Let me provide you with more context to better understand the problem.
Summaries Error:
Error Message: TypeError: res.setHeader is not a function
File: src/app/api/auth/logout/route.tsx
Probable Cause:
The error suggests that there’s an issue with the res object within the logout route. It seems like the res object doesn’t have the expected setHeader function. This typically indicates a mismatch between the expected and actual object types.
path: src/app/api/auth/logout/route.tsx
export async function GET(req: NextApiRequest, res: NextApiResponse) {
try {
res.setHeader(
"Set-Cookie",
`${COOKIE_NAME}=; Path=/; Expires=Thu, 01 Jan 1970 00:00:00 GMT`
);
res.writeHead(302, { Location: "/login" });
res.end();
} catch (error) {
console.error("Logout error:", error);
res.status(500).json({ message: "Internal Server Error" });
}
}
path: src/app/components/LeftPanel.tsx
import React from 'react';
import { Button } from "../../components/ui/button"
import './style.css';
import { useRouter } from 'next/navigation';
const LeftPanel: React.FC = () => {
const { push } = useRouter();
const handleLogout = async () => {
try {
const response = await fetch('/api/auth/logout', {
method: 'GET',
});
if (response.ok) {
window.alert('Logout successful! Click OK to go to the login page.');
console.log('response', response);
push('/login');
}
} catch (error) {
console.error("Logout error:", error);
// Handle any potential errors
}
};
return (
<div className="left-panel">
<Button onClick={handleLogout}>Logout</Button>
</div>
);
};
export default LeftPanel;
