Estoy tratando de enviar una solicitud al servidor para guardar una publicación. Estoy usando Nextjs y cada vez que intento enviarlo me da este error [ERR_HTTP_HEADERS_SENT]: no se pueden establecer encabezados después de que se envían al cliente.

Aquí está mi código

 Post.js async function uploadPost(post) { const response = await fetch('/api/savePost', { method: 'POST', body: post, }); if(!response.ok) { throw new Error('Failed to post') } return await response.json();

}

 savePost.js export const config = { api: { bodyParser: false, }, } export default const post = async (req, res) => { if (req.method !== 'POST') { return res.status(405).json({ message: 'Method not allowed' }) } // const postData = JSON.parse(req.body); const savedPost = await prisma.post.create({ data: req.body }); res.status(200).json({message: 'Post saved successfully'}) res.json(savedPost) };

Estoy usando Prisma para la base de datos. Me sale este error.
