...Hello.
I have created an app at Facebook developer is built in asp.net core . I have a client set up to be authorized with that IdentityServer.
Now when i try to access a secure resource on client application, identity server redirects me to my identityserver website. There i try to authenticate via Facebook . After logging in, Facebook asks for the persmission that my identityserver needs to access . If i allow there, it all works fine .
But the issue arises when i click deny, then Facebook app redirects to my identity server website with error="access_denied" in querystring and my identityserver website throws exception
regarding that access denied error.
How can I handle that situation given the fact that I do not allow the application to access information at Faceboook? Thanks.
