Implementing Google OAuth throws an error after logging in

I'm losing my mind over this, I'm sure it's a minor fix but I can't seem to get it working, I've setup the Google OAuth controller, and everything seems to be working at glance, the application builds, the url gets me to google, i can select my account, but once it tries to call the callback, it says the oauth state is missing or invalid https://github.com/lumijiez/raven/blob/dev/auth/server/Raven/Raven.Auth/Controllers/GoogleOAuthController.cs https://github.com/lumijiez/raven/blob/dev/auth/server/Raven/Raven.Auth/Startup.cs here are the relevant files

if think instead of setting "options.CallbackPath = "/oauth/google/callback";" inside AddGoogle. Remove setting that CallbackPath. and just use the RedirectUri that u set in the AuthenticationProperties. It will then correctly first redirect to the internal path of default value of CallbackPath and then to your endpoint.

that wont work because im not using the default google url, so i need to put it there, if i remove the callback path setting, google just shows a redirect mismatch

Then you might need to check to do that properly because that setting is: CallbackPath is not supposed to refer to a controller, it refers to a unique path handled by the auth middleware (defaults to /signin-google). It will redirect back to your controller when it's done.

ohh, i see then

 public IActionResult Login()
        {
            var redirectUrl = Url.Action("Callback", "GoogleOAuth");
            var properties = new AuthenticationProperties
            {
                RedirectUri = redirectUrl
            };
            return Challenge(properties, GoogleDefaults.AuthenticationScheme);
        }

 public IActionResult Login()
        {
            var redirectUrl = Url.Action("Callback", "GoogleOAuth");
            var properties = new AuthenticationProperties
            {
                RedirectUri = redirectUrl
            };
            return Challenge(properties, GoogleDefaults.AuthenticationScheme);
        }

so, it means this returns a wrong url if im getting a mismatch right?

maybe you could rename your callback and keep the options.CallbackPath = "/oauth/google/callback"; in so the internal middleware catches /oauth/google/callback im sorry, im bad with terms let me rephrase
