Next-auth: Overwrite user object in session

[jjzcru]

Your question
There is a way to overwrite the existing user object in session?

What are you trying to do
I'm creating a multitenant application and I need to store the TenantID in the session but I'm unable to add another property besides name, email and picture

@jjzcru This is how I'm doing it using a custom provider:

const options = {
  site: BASE_URL,
  providers: [
    {
      ...
      profile: (profile: Record<string, string>) => {
        return { ...profile, id: profile.sub };
      },
    }
  ],
  callbacks: {
    session: async (
      session: SessionBase,
      user: Record<string, string>,
    ): Promise<GenericObject> => {
      user.id = user.sub;
      session.user = user;
      return Promise.resolve(session);
    },
    jwt: async (
      token: GenericObject,
      user: User,
      account: GenericObject,
      profile: GenericObject,
    ): Promise<GenericObject> => {
      return Promise.resolve(profile ? profile : token);
    },
  },
};

Ignore the types if you're not using typescript.

In this example, I'm adding the attribute id to the user. You can add attributes to the session in the session callback.
