I am trying to setup Node/Express server side web application with custom login screen. And i am using ExpressOIDC router config as below to define custom login view handler: ```auto const oidc = new ExpressOIDC({ issuer: process.env.OIDC_ISSUER, client_id: process.env.OIDC_CLIENT_ID, client_secret: process.env.OIDC_CLIENT_SECRET, appBaseUrl: process.env.BASE_URL, scope: 'openid profile email', routes: { login: { viewHandler: (req, res) => { const baseUrl = url.parse(process.env.OIDC_ISSUER).protocol + '//' + url.parse(process.env.OIDC_ISSUER).host; // Render your custom login page, you must create this view for your application and use the Okta Sign-In Widget res.render('login1', { csrfToken: req.csrfToken(), baseUrl: baseUrl, clientId: process.env.OIDC_CLIENT_ID, redirectUri: process.env.BASE_URL+'/callback', issuer: process.env.OIDC_ISSUER }); } } loginCallback: { path: '/callback', failureRedirect: '/', afterCallback: '/users' }, ``` And i followed the below link to setup the login view [https://developer.okta.com/code/javascript/okta\_sign-in\_widget/#server-side-web-application-using-authorization-code-flow](https://developer.okta.com/code/javascript/okta_sign-in_widget/#server-side-web-application-using-authorization-code-flow) ```auto

``` I am getting the custom login screen and after entering the credentials and clicking the login button, its authenticating successfully and trying to redirect to the callback route, and i am getting an error “Error Error: did not find expected authorization request details in session, req.session[“oidc:[https://dev-85865421.okta.com/oauth2/default](https://dev-85865421.okta.com/oauth2/default)”] is undefined” ![image](https://global.discourse-cdn.com/oktadev/original/2X/4/44ba0afd25609313840883d38386f82b25c7051b.png) The same code works perfectly after commenting out the login viewhandler code, which shows the OKTA hosted login screen. Any help or hint would be really appreciated. Also i am looking to setup custom login screen without OKTA widget. Please show me the right direction to implement the same ---

After doing some investigation, what i noticed is when i click login button from home page to show the login widget, in the server side session store data an entry is made with key “oidc:[https://dev-85865421.okta.com/oauth2/default](https://dev-85865421.okta.com/oauth2/default)” only when i use OKTA hosted widget. If i use the custom login widget , this session store data is missing. ---
