Problem in navigate to login page after redirect

[majidebraa]

I place callback.html in the web folder and when I try to run in localhost after login user in the identity server(SSO) gets this error and the login goes incomplete.

Could not navigate to initial route.
The requested route name was: "/callback.html?code=3FB8C2350B5BAB64BA451D1AB7DA3D6DC64972068FEB54D9A0F9F04236788603&scope=openid%20profile%20email%20roles%20offline_access&session_state=pnUxDeiG5WF-1Devzs7829Rwnf9ZxxjPvA-1okPvgBI.BDF625AA8B19E06D8D8FE69B0CEF6E5E"
There was no corresponding route in the app, and therefore the initial route specified will be ignored and "/" will be used instead.

If you modify the sample app included does it cause the problem? If not, please modify the sample to reproduce.
