BadRequestError: checks.state argument is missing when logging in [RP]

i do indeed! all info is stored in config files or ENV so don’t worry about that.
forgot to mention - CF plan is free.

const aconf = {
    authRequired: config.authZero.authRequired,
    auth0Logout: config.authZero.auth0Logout,
session: {
    //@ts-ignore
    cookie: {
      domain: '.recipe-realm.com'
    }
  },
    secret: process.env.secret,
    baseURL: config.authZero.baseURL,
    clientID: process.env.clientId,
    issuerBaseURL: config.authZero.issuerBaseURL
  };
app.use(auth(aconf));
