discord login is working just fine, i added the credentials provider to the providers array, like this:

CredentialsProvider({
    name: 'username and password',
    credentials: {
        username: { label: 'username', type: 'text' },
        password: { label: 'password', type: 'password' },
    },
    async authorize(credentials, req) {
        return { id: '1234', name: 'John Doe', email: 'john@gmail.com' }
    },
}),

then i go to /api/auth/signin, but it doesnt create the jwt cookie. the session callback is never called for some reason. any idea what might be happening? (im using create-t3-app btw)
