User, Account, Profile are undefined in jwt() callback

[BaltsevichDanil]

Hello. I am using login with сredentials and want to add some additional data to user in jwt() callback. But all fields are undefined except token. Please help me to solve this problem.

import NextAuth from 'next-auth'
import Providers from 'next-auth/providers'

export default NextAuth({
  providers: [
    Providers.Credentials({
      name: 'Credentials',
      authorize: async (_, req) => {
        const user = {
          email: req.body.email,
          password: req.body.password,
          some: 'fsjdfkldsjfklds',
        }
        if (user) {
          return user
        } else {
          return null
        }
      },
    }),
  ],

  secret: process.env.SECRET,
  session: {
    jwt: true,
  },
  jwt: {
    encryption: true,
    secret: process.env.SECRET,
  },
  callbacks: {
    async signIn(user) {
      return JSON.stringify(user)
    },
    async jwt(token, user, account, profile) {
      console.log(user, account, profile) // undefined undefined undefined
      if (account) {
        token.accessToken = account?.accessToken
      }
      return token
    },
    async session(session, token) {
      session.accessToken = token.accessToken
      return session
    },
  },

  debug: true,
})
