Hello,
I'm implementing login using Azure AD B2C following https://support.aspnetzero.com/QA/Questions/7702
AspNetZero version 10.3 AspNet Core Mvc + Jquery
in appsettings.json I have
"OpenId": {
"IsEnabled": "true",
"ClientId": "f796d474-8c95-4779-a895-71a0ec8d56b6",
"ClientSecret": "xxx xxx xxx",
"Authority": "https://b2clogin.b2clogin.com/b2clogin.onmicrosoft.com/oauth2/v2.0/authorize",
"ValidateIssuer": "false"
}
the login flow can be tested here https://optima4labs.b2clogin.com/optima4labs.onmicrosoft.com/v2.0/.well-known/openid-configuration?p=B2C_1_portal_userflow
when I try to click OpenId button from the login form I expect to be redirected to the azure login but instead I get this error:
An unhandled exception occurred while processing the request.

Dear @luca.teodori,
I was getting the exact same error too. The only way I could get Azure B2C to work so far is implement the code provided by @ismcagdas in ticket https://support.aspnetzero.com/QA/Questions/9789/Azure-B2C-OpenId-new-user-login-failing
I implemented the code mentioned above and called my own "GetUserInfo" method rather calling the abp code. I changed a line in @ismcagdas' code:
From: var issuer = ProviderInfo.AdditionalParams["Authority"];
To: var issuer = "https://<myTenantName>.b2clogin.com/<myTenantName>.onmicrosoft.com/<PolicyName>";
Here are my appsettings.json for "OpenId":
"IsEnabled": "true", "ClientId": "<AppRegistrationClientId>", "Authority": "https://<myTenantName>.b2clogin.com/<myTenantId>/v2.0/", "LoginUrl": "https://<myTenantName>.b2clogin.com/tfp/<myTenantName>.onmicrosoft.com/<PolicyName>/oauth2/v2.0/authorize",
In Azure B2C, I had to create an App Registration and a Sign-in "User Flows"
Kind Regards,
Darrell

Hello Darrell, thanks for your help, I think I have a different problem: the exception occurs before I get redirected to Atzure B2C for user authentication

oh sorry Luca, yesterday I was getting the exact same error on the following line in TokenAuthController.cs
private async Task<ExternalAuthUserInfo> GetExternalUserInfo(ExternalAuthenticateModel model) { var userInfo = await _externalAuthManager.GetUserInfo(model.AuthProvider, model.ProviderAccessCode);
