const A = await Promise.all(accountUsers.map(async (user) =>  {
    const { state, csrfSecret } = await oauth.generateState();

    return {
        accountId: user.accountId,
        firstName: user.firstName,
        lastName: user.lastName,
        email: user.email,
        csrfSecret,
        state,

const B =  A.map((user) => { 
    return {
        user.accountId,
        user.firstName,
        user.lastName,
        user.email,
