Nextauth token keeps on nesting

Question

I updated with v4 beta with next-auth. But the token keeps on nesting on refresh, as in token converts to token.token to token.token.token .... on each refresh for some reason

jwt: async (token, user, account, profile, isNewUser) => {
      return token; 
    },

Answer 1

From version 3 to 4 the default function of jwt changed from

async jwt(token, user, account, profile, isNewUser) {
  return token
}

to

 async jwt({ token, user, account, profile, isNewUser }) {
  return token
}

Suggesting that you should take the token out of the first parameter using deconstruction instead of returning the whole thing.
