Access denied when permission of app to my application is denied with Facebook authentication in core


I have created an app at Facebook developer  is built in 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.
